Ошибка при изменении часового пояса в Windows Server 2019

Добрый день! Уважаемые читатели и гости одного из крупнейших русскоязычных IT блогов Pyatilistnik.org. В прошлый раз мы с вами разобрали, как производится подключение к удаленному рабочему столу с ноутбука или компьютера, на котором установлена Windows 10. Идем дальше и поговорим про смену часовых поясов в Windows Server 2019, вроде простая вещь, но вы легко можете столкнуться с ситуацией, что имея административные права вы просто не можете это сделать с помощью штатных средств, получая ошибку «У вас нет разрешения на выполнение этой задачи. Обратитесь за помощью к сетевому администратору«.

Ошибка при изменении часового пояса в Windows Server 2019

Случился со мной интересный случай, я развернул Windows Server 2019 на двух новых серверах Dell Power Edge R740, исправил на них ошибку в работе Nic Teaming и перешел к настройке кластера под MS SQL 2019. После того, как кластер был развернут я заметил, что по какой-то причине у меня на серверах отображается не правильное время, хотя в локальной сети есть NTP сервер. Я для быстроты настройки решил просто в ручном режиме выбрать нужный часовой пояс, но настройки почему-то не сохранялись, а при попытке их выбрать через оснастку «Дата и время» я получал ошибку:

You do not have permission to perform to perform this task. Contact your network administrator for help

You do not have permission to perform to perform this task. Contact your network administrator for help

В русском варианте это звучит вот так:

«У вас нет разрешения на выполнение этой задачи. Обратитесь за помощью к сетевому администратору».

У вас нет разрешения на выполнение этой задачи. Обратитесь за помощью к сетевому администратору

Самое интересное, что политик в явном виде на эти сервера не прилетало и я имел в системе полные, административные права. Давайте разбираться, как установить часовой пояс в Windows Server 2019 и выше.

Настройка часового пояса через панель «Параметры Windows»

Самый базовый метод выбора нужного часового пояса, это через окно «Параметры Windows«, чтобы в него попасть просто нажмите одновременно клавиши Win и I.

Параметры Windows

Далее вы выбираете «Дата и время«, где в поле «Изменить дату и время» вы можете установить необходимый часовой пояс, но в моем случае, данная настройка просто не сохранялась, поэтому пришлось вернуться, к старому, проверенному методу.

Дата и время в параметрах Windows

Как поменять часовой пояс через классическую оснастку «Дата и время»

Второй рабочий метод позволяющий задать нужный часовой пояс и время, является вызов классического окна «Дата и время«, я буду использовать его потому, что в панели управления Windows Server 2019 исчезла вкладка «Местоположение«, которая помогала в нашей задаче.

Вкладка местоположение в Windows Server 2019

Откройте обязательно командную строку или оболочку PowerShell от имени администратора, чтобы не получать ошибку «У вас нет разрешения на выполнение этой задачи. Обратитесь за помощью к сетевому администратору» и введите команду:

В результате у вас будет классическое окно для установки даты и времени, которое Microsoft тщательно скрыло. Теперь выставите без проблем нужный вам часовой пояс.

Оснастка timedate.cpl

Как настроить часовой пояс через командную строку

В командной строке есть утилита tzutil.exe, которая используется для изменения часового пояса. Ее использование относительно простое. Так же запустите командную строку в режиме администратора и введите:

В результате вы получите список доступных часовых поясов. Вам необходимо найти нужный, в моем случае, это «UTC+03:00) Moscow, St. Petersburg Russian Standard Time».

Вывод списка часовых поясов через утилиту tzutil /l

Кстати если вы точно знаете ключевое слово, то можете его использовать, например вот так:

tzutil /l | findstr Moscow

Кстати если добавите ключ _dstoff, то можно отключить переход на летнее время для конкретного пояса

Вывод списка часовых поясов через утилиту tzutil /l

Теперь установим данный часовой пояс в нашей Windows Server 2019.

tzutil /s «(Russian Standard Time»

Установка часового пояса в командной строке

Как настроить часовой пояс через PowerShell

Давайте попробуем изменить часовой пояс через средства оболочки PowerShell. Для этой цели служат командлеты Get-TimeZone и Set-TimeZone. Давайте для начала найдем нужный нам часовой пояс, для этого введите:

Get-TimeZone -ListAvailable | where DisplayName -like «*Moscow*»

Как видим нужный нам часовой пояс имеет StandardName «Russia TZ 2 Standard Time».

Вывод список часовых поездов в PowerShell

Далее установим нужный нам часовой пояс, для этого вводим команду:

Set-TimeZone -Name «Russia TZ 2 Standard Time»

Как настроить часовой пояс через PowerShell

Можно и такой конструкцией:

Get-TimeZone -ListAvailable | ? DisplayName -like «*Moscow*» | Set-TimeZone

Настройка часового пояса через реестр Windows

Давайте я еще покажу, что именно меняется в реестре, когда вы задаете нужный часовой пояс. В окне выполнить введите regedit, далее идем в ветку:

ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSet ControlTimeZoneInformation

тут есть ключ «TimeZoneKeyName» с типом REG_SZ и значением, в моем примере, это московское время «Russian Standard Time».

Настройка часового пояса через реестр Windows

Настройка часового пояса через групповую политику

Если вы захотите с помощью средств GPO настроить нужный часовой пояс на серверах с Windows Server 2019, то вам в политике просто нужно создать ключ реестра с нужным значением, который я описал выше. Если у вас на RDS ферме пользователи разных часовых поясов, то для их удобства вы можете брать время на RDSH хосты с их систем откуда они подключаются, для этого воспользуйтесь групповой политикой

«Разрешить перенаправление часового пояса (Конфигурация компьютера> Политики -> Административные шаблоны -> Компоненты Windows -> Службы удаленного рабочего стола -> Узел сеанса удаленного рабочего стола -> Перенаправление устройств и ресурсов (Allow time zone redirection (Computer Configuration > Policies -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Device and Resource Redirection)».

Так, что если вы видите в системе ошибку «У вас нет разрешения на выполнение этой задачи. Обратитесь за помощью к сетевому администратору», это еще не значит, что у вас нет прав. На этом у меня все, с вами был Иван Сёмин, автор и создатель IT портала Pyatilistrnik.org.

У начинающих системных администраторов при виде этой ошибки могут возникнуть приступы неудержимого смеха, беспричинной паники, или заторможенности. Дело в том, что системный администратор, видя совет обратиться к администратору компьютера, начинает рекурсивно обращаться сам к себе.

В программировании рекурсия, или рекурсивная функция — это такая функция, которая вызывает саму себя.

Бывалый системный администратор просто понимает, что операционная система предлагает найти ответ самому. И начинает действовать. Я вспоминаю, что компаний Microsoft с каждым новым обновлением переносит часть функционала в интерфейс Метро. Перехожу в настройки Windows из меню Пуск.

win

Time & Language. Date & Time.

win

Здесь тоже есть поле для изменения временной зоны. Меняю часовой пояс. Выхожу из меню настроек и понимаю, что часовой пояс не изменился. Винда просто пугает! Вот тут-то бывалый системный администратор тоже может зависнуть, захихикать или забыть как кликать мышкой. Это нормально, это одна из стратегий поведения при реакции на страх. Замереть, бежать или напасть. Бежать не от кого, нападать тоже не на кого, поэтому сисадмин находится в прострации и тупит.

Прострация — это понятие в медицине, означающие состояние эмоциональной опустошённости.

Но профессиональный системный администратор уже давно не боится винду. И начинает думать. Это естественное поведение системного администратора, сначала сделать, а если не получилось, то подумать. Я начинаю осмысливать текст первоначальной ошибки и понимаю, что прав не хватает. А прав тот, у кого больше прав. Правильно, нужно повысить права.

Запускаю командную строку от имени Администратора и выполняю команду:

timedate.cpl

win

CPL это сокращение от Control Panel. Вызывается окно управления датой и временем из панели управления. Снова пытаюсь изменить часовой пояс.

win

На этот раз временная зона успешно изменяется.

Сегодня мы с вами научились изменять часовой пояс в Windows Server 2019. И заодно узнали два новых термина: «рекурсия» и «прострация».

How to Configure NTP Server on Windows Server 2019

Network Time Protocol (NTP) runs on the Transport Layer port 123 UDP and enables accurate time synchronization for network computers. This irons out time inconsistencies on servers and clients during file logging or replication of server databases among other resources.

In this article, we’ll outline the process of installing, configuring, and querying an NTP server on Windows Server 2019.

NTP Server

NTP servers utilize the Network Time Protocol to send time signals to servers across the globe upon request. NTP servers use the Universal Time Coordinated (UTC) time source for time signal synchronization.

The main purpose of NTP servers is to provide time synchronization for servers and computer networks with other major network servers and clients across the globe. In turn, this streamlines communications and transactions all over the world.

Installing and Configuring an NTP Server on Windows Server 2019

The process of installing, configuring, and querying an NTP Server on Windows Server 2019 is quite straightforward.

Set the NTP service to Automatic option

To start off, Hit Windows Key + R to launch the Run dialogue. Next, type services.msc and hit ENTER.

In the ‘Services’ window, locate the service ‘Windows Time’. Right-click and select the ‘Properties’ option as shown:

On the pop-up window, select the Startup type as ‘Automatic’.

Finally, click on ‘OK’ and then ‘Apply’.

Configuring NTP Server using Registry Editor

As before, launch the run dialogue by pressing Windows Key + R. Then type ‘regedit’ and hit ENTER.

The Registry editor will be launched as shown:

Navigate to the path shown below:

ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNtpServer

On the right pane, locate and double-click the ‘Enabled’ file as shown:

Set the Value data to 1 and click OK.

Next, follow this path.

Computer>HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Services>W32Time>Config

At the right pane locate the ‘Announce Flags’ file.

Double click on the file and set its value to 5 in the ‘Value Data’ section.

Finally, reboot the NTP server for the changes to take place. Head back to the services Window, right-click on ‘Windows Time’ and select ‘Restart

Configuring NTP Server on Windows 2019 using Windows PowerShell

If you love working in Powershell, launch Powershell as Administrator and enable NTP server using the command:

Set-ItemProperty -Path “HKLM:SYSTEMCurrentControlSetServicesw32timeTimeProvidersNtpServer” -Name “Enabled” -Value 1

Next, configure Announce Flags value as shown:

Set-ItemProperty -Path “HKLM:SYSTEMCurrentControlSetservicesW32TimeConfig” -Name “AnnounceFlags” -Value 5

Finally, restart the NTP server using the command:

Restart-Service w32Time

Important Note: UDP port 123 must be open for the NTP server traffic to reach your Windows Server 2019. If the NTP servers are unreachable, you can check your firewall settings to fix this.

Other useful commands

  1. w32tm /query /configuration to check and shows the NTP server configuration.
  2. w32tm /query /peers for checking the list of NTP servers configured alongside their configuration status
  3. w32tm /resync /nowait to force-synchronize time with your NTP server.
  4. w32tm /query /source to show the source of the time.
  5. w32tm /query /status to reveal NTP time service status.

Final take

Now your Windows Server 2019 clock is synchronized with time the NTP server’s pool.ntp.org and works as NTP client. You can achieve full network and accompanying infrastructure time synchronization by synchronizing all network workstations, servers, routers, hubs, and switches.

Since NTP servers operate over the UDP protocol using TCP/IP, these network infrastructures must be working efficiently for effective NTP server operation. In case you want to make time servers on windows server 2019 hosted on a virtual machine, you should disable the virtual machine time synchronization settings and sync their time with the domain Windows Server 2019.

The Windows Time service (W32Time) synchronizes the date and time for all computers managed by Active Directory Domain Services (AD DS). This article covers the different tools and settings used to manage the Windows Time service.

By default, a computer that is joined to a domain synchronizes time through a domain hierarchy of time sources. However, if a computer has been manually configured to synchronize from a specific time source, perhaps because it was formerly not joined to a domain, you can reconfigure the computer to begin automatically sourcing its time from the domain hierarchy.

Most domain-joined computers have a time client type of NT5DS, which means that they synchronize time from the domain hierarchy. An exception to this is the domain controller, which functions as the primary domain controller (PDC) emulator operations master for the root forest domain. The PDC emulator operations master in turn is configured to synchronize time with an external time source.

You can achieve down to one-millisecond time accuracy in your domain. For more information, see Support boundary for high-accuracy time and see Accurate Time for Windows Server 2016.

Don’t use the Net time command to configure or set a computer’s clock time when the Windows Time service is running.

Also, on older computers that run Windows XP or earlier, the Net time /querysntp command displays the name of a Network Time Protocol (NTP) server with which a computer is configured to synchronize, but that NTP server is used only when the computer’s time client is configured as NTP or AllSync. This command has since been deprecated.

Network port

The Windows Time service follows the Network Time Protocol (NTP) specification, which requires the use of UDP port 123 for all time synchronization. Whenever the computer synchronizes its clock or provides time to another computer, it happens over UDP port 123. This port is exclusively reserved by the Windows Time service.

  • If you have a computer with multiple network adapters (is multi-homed), you cannot enable the Windows Time service based on a network adapter.
  • The Windows Time NTP client uses UDP port 123 for both source and destination sync requests. When using network filtering, be aware of the source port being used.

Using W32tm.exe

You can use the command-line tool W32tm.exe to configure Windows Time service settings and to diagnose computer time problems. W32tm.exe is the preferred command-line tool for configuring, monitoring, and troubleshooting the Windows Time service. W32tm.exe is included with Windows XP and later and Windows Server 2003 and later.

Membership in the local Administrators group is required to run W32tm.exe locally, while membership in the Domain Admins group is required to run W32tm.exe remotely.

Run W32tm.exe

  1. In the Windows search bar, enter cmd.
  2. Right-click Command Prompt, then select Run as administrator.
  3. At the command prompt, enter w32tm followed by the applicable parameter, as described below:

Set client to use two time servers

To set a client computer to point to two different time servers, one named ntpserver.contoso.com and another named clock.adatum.com , type the following command at the command prompt, and then press ENTER:

Set client to sync time automatically from a domain source

To configure a client computer that is currently synchronizing time using a manually-specified computer to synchronize time automatically from the AD domain hierarchy, run the following:

Check client time configuration

To check a client configuration from a Windows-based client computer that has a host name of contosoW1 , run the following command:

The output of this command displays a list of W32time configuration parameters that are set for the client.

Windows Server 2016 has improved the time synchronization algorithms to align with RFC specifications. Therefore, if you want to set the local time client to point to multiple peers, we recommended that you prepare three or more different time servers.

If you have only two time servers, you should specify the Ntpserver UseAsFallbackOnly flag (0x2) to de-prioritize one of them. For example, if you want to prioritize ntpserver.contoso.com over clock.adatum.com , run the following command:

Additionally, you can run the following command and read the value of NtpServer in the output:

Configure computer clock reset

In order for W32tm.exe to reset a computer clock, it first checks the offset ( CurrentTimeOffset , also known as Phase Offset ) between the current time and the computer clock time to determine whether the offset is less than the MaxAllowedPhaseOffset value.

  • CurrentTimeOffset ≤ MaxAllowedPhaseOffset : Adjust the computer clock gradually by using the clock rate.
  • CurrentTimeOffset > MaxAllowedPhaseOffset : Set the computer clock immediately.

Then, to adjust the computer clock by using the clock rate, W32tm.exe calculates a PhaseCorrection value. This algorithm varies depending on the version of Windows:

Windows Server 2016 and later versions:

PhaseCorrection_raw = | CurrentTimeOffset | Г· (16 Г— PhaseCorrectRate Г— pollIntervalInSeconds )
MaximumCorrection = | CurrentTimeOffset | Г· ( UpdateInterval Г· 100)
PhaseCorrection = min( PhaseCorrection_raw , MaximumCorrection )

Windows Server 2012 R2 and earlier versions:

To get the SystemClockRate value, you can use the following command and convert it from seconds to clock ticks by using the formula of (seconds Г— 1,000 Г— 10,000):

PhaseCorrection = | CurrentTimeOffset | Г· ( PhaseCorrectRate Г— UpdateInterval )

All versions of Windows use the same final equation to check PhaseCorrection :

PhaseCorrection ≤ SystemClockRate ÷ 2

Windows Server 2019 and Windows 10 1809 have the same formula as [Windows Server 2016 and later versions] described above by applying cumulative updates from KB5006744 onwards.

These equations use PhaseCorrectRate , UpdateInterval , MaxAllowedPhaseOffset , and SystemClockRate measured in units of clock ticks. On Windows systems, 1 ms = 10,000 clock ticks.

MaxAllowedPhaseOffset is configurable in the registry. However, the registry parameter is measured in seconds instead of clock ticks.

To see the SystemClockRate and pollIntervalInSeconds values (measured in seconds), open a Command Prompt window and then run W32tm /query /status /verbose . This command produces output that resembles the following.

The output presents the poll interval in both clock ticks and in seconds. The equations use the value measured in seconds (the value in parentheses).
The output presents the clock rate in seconds. To see the SystemClockRate value in clock ticks, use the following formula:

( value in seconds ) Г— 1,000 Г— 10,000

For example, if SystemClockRate is 0.0156250 seconds, the value that the equation uses is 156,250 clock ticks. For full descriptions of the configurable parameters and their default values, see Config entries later in this article.

The following examples show how to apply these calculations for Windows Server 2012 R2 and earlier versions.

Example: System clock rate off by four minutes

Your computer clock time is 11:05 and the actual current time is 11:09:

UpdateInterval = 30,000 clock ticks

SystemClockRate = 156,000 clock ticks

MaxAllowedPhaseOffset = 10 min = 600 seconds = 600 Г— 1,000 Г— 10,000 = 6,000,000,000 clock ticks

| CurrentTimeOffset | = 4 min = 4 Г— 60 Г— 1,000 Г— 10,000 = 2,400,000,000 clock ticks

Is CurrentTimeOffset ≤ MaxAllowedPhaseOffset ?

AND does it satisfy the following equation?

(| CurrentTimeOffset | ÷ ( PhaseCorrectRate × UpdateInterval ) ≤ SystemClockRate ÷ 2)

Is 2,400,000,000 / (30,000 × 1) ≤ 156,000 ÷ 2

80,000 ≤ 78,000: FALSE

Therefore, W32tm.exe would set the clock back immediately.

In this case, if you want to set the clock back slowly, you would also have to adjust the values of PhaseCorrectRate or UpdateInterval in the registry to make sure that the equation result is TRUE.

Example: System clock rate off by three minutes

Your computer clock time is 11:05 and the actual current time is 11:08:

UpdateInterval = 30,000 clock ticks

SystemClockRate = 156,000 clock ticks

MaxAllowedPhaseOffset = 10 min = 600 seconds = 600 Г— 1,000 Г— 10,000 = 6,000,000,000 clock ticks

| CurrentTimeOffset | = 3 mins = 3 Г— 60 Г— 1,000 Г— 10,000 = 1,800,000,000 clock ticks

Is CurrentTimeOffset ≤ MaxAllowedPhaseOffset ?

AND does it satisfy the following equation?

(| CurrentTimeOffset | ÷ ( PhaseCorrectRate × UpdateInterval ) ≤ SystemClockRate ÷ 2)

(1,800,000,000) ÷ (1 × 30,000) ≤ 156,000 ÷ 2

In this case, the clock will be set back slowly.

Using Local Group Policy Editor

The Windows Time service stores several configuration properties as registry entries. You can use Group Policy Objects (GPOs) in Local Group Policy Editor to configure most of this information. For example, you can use GPOs to configure a computer to be an NTPServer or NTPClient, configure the time synchronization mechanism, or configure a computer to be a reliable time source.

Group Policy settings for the Windows Time service can be applied on Windows Server 2003, Windows Server 2003 R2, Windows Server 2008, and Windows Server 2008 R2 domain controllers and can be applied to computers running Windows Server 2003, Windows Server 2003 R2, Windows Server 2008, and Windows Server 2008 R2.

Windows stores the Windows Time service policy information in the Local Group Policy Editor under Computer ConfigurationAdministrative TemplatesSystemWindows Time Service . It stores configuration information that the policies define in the Windows registry, and then uses those registry entries to configure the registry entries specific to the Windows Time service. As a result, the values defined by Group Policy overwrite any pre-existing values in the Windows Time service section of the registry. Some of the preset GPO settings differ from the corresponding default Windows Time service registry entries.

For example, suppose you edit policy settings in the Time ProvidersConfigure Windows NTP Client policy. Windows loads these settings into the policy area of the registry under the following subkey:

Then Windows uses the policy settings to configure the related Windows Time service registry entries under the following subkey:

The following table lists the policies that you can configure for the Windows Time service, and the registry subkeys that those policies affect.

When you remove a Group Policy setting, Windows removes the corresponding entry from the policy area of the registry.

Windows registry reference

This information is provided as a reference for use in troubleshooting and validation. Windows registry keys are used by W32Time to store critical information. Don’t change these values. Modifications to the registry are not validated by the registry editor or by Windows before they are applied. If the registry contains invalid values, Windows may experience unrecoverable errors.

The Windows Time service stores information in the registry at the HKLMSYSTEMCurrentControlSetServicesW32Time path under the following subkeys:

In the following tables, «All versions» refers to Windows 7, Windows 8, Windows 10, Windows Server 2008 and Windows Server 2008 R2, Windows Server 2012 and Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019.

Some of the parameters in the registry are measured in clock ticks and some are measured in seconds. To convert the time from clock ticks to seconds, use these conversion factors:

  • 1 minute = 60 sec
  • 1 sec = 1000 ms
  • 1 ms = 10,000 clock ticks on a Windows system, as described at DateTime.Ticks Property.

For example, 5 minutes becomes 5 Г— 60 Г— 1000 Г— 10000 = 3,000,000,000 clock ticks.

Config entries

The Config subkey entries are located at HKLMSYSTEMCurrentControlSetServicesW32TimeConfig .

Registry entry Versions Description
AnnounceFlags All versions Controls whether this computer is marked as a reliable time server. A computer is not marked as reliable unless it is also marked as a time server.

  • 0x00. Not a time server
  • 0x01. Always time server
  • 0x02. Automatic time server
  • 0x04. Always-reliable time server
  • 0x08. Automatic reliable time server

The default value for domain members is 10. The default value for stand-alone clients and servers is 10.

ChainDisable Controls whether or not the chaining mechanism is disabled. If chaining is disabled (set to 0), a read-only domain controller (RODC) can synchronize with any domain controller, but hosts that do not have their passwords cached on the RODC will not be able to synchronize with the RODC. This is a boolean setting, and the default value is .
ChainEntryTimeout Specifies the maximum amount of time that an entry can remain in the chaining table before the entry is considered to be expired. Expired entries may be removed when the next request or response is processed. The default value is 16 (seconds).
ChainLoggingRate Controls the frequency at which an event that indicates the number of successful and unsuccessful chaining attempts is logged to the System log in Event Viewer. The default is 30 (minutes).
ChainMaxEntries Controls the maximum number of entries that are allowed in the chaining table. If the chaining table is full and no expired entries can be removed, any incoming requests are discarded. The default value is 128 (entries).
ChainMaxHostEntries Controls the maximum number of entries that are allowed in the chaining table for a particular host. The default value is 4 (entries).

The default value for domain members is 10. The default value for stand-alone clients and servers is 10.
PhaseCorrectRate All versions Controls the rate at which the phase error is corrected. Specifying a small value corrects the phase error quickly, but might cause the clock to become unstable. If the value is too large, it takes a longer time to correct the phase error.

The default value on domain members is 1. The default value on stand-alone clients and servers is 7.

Note
Zero is not a valid value for the PhaseCorrectRate registry entry. On Windows Server 2003, Windows Server 2003 R2, Windows Server 2008, and Windows Server 2008 R2 computers, if the value is set to , the Windows Time service automatically changes it to 1.

Enhanced logging

The following registry entries are not a part of the W32Time default configuration but can be added to the registry to obtain enhanced logging capabilities. The information logged to the System Event log can be modified by changing values for the EventLogFlags setting in the Group Policy Object Editor. By default, the Windows Time service logs an event every time that it switches to a new time source.

In order to enable W32Time logging, add the following registry entries:

Entry Versions Description
FileLogEntries All versions Controls the number of entries created in the Windows Time log file. The default value is none, which does not log any Windows Time activity. Valid values are to 300. This value does not affect the event log entries normally created by Windows Time
FileLogName All versions Controls the location and file name of the Windows Time log. The default value is blank, and should not be changed unless FileLogEntries is changed. A valid value is a full path and file name that Windows Time will use to create the log file. This value does not affect the event log entries normally created by Windows Time.
FileLogSize All versions Controls the circular logging behavior of Windows Time log files. When FileLogEntries and FileLogName are defined, defines the size, in bytes, to allow the log file to reach before overwriting the oldest log entries with new entries. Please use 1000000 or larger value for this setting. This value does not affect the event log entries normally created by Windows Time.

Group Policy Object settings

Часовой пояс (Time zone), наряду с временем и датой, это один из критический параметров компьютера. Для корректной работы Windows/прикладных программ и правильного отображения времени в системе, часовой пояс должен быть установлен в соответствии с географическим расположением компьютера. В этой статье мы рассмотрим, как изменить часовой пояс в Windows из графического интерфейса, командной строки, консоли PowerShell и с помощью групповых политик.

В Windows 10 и Windows Server 2019/2016 для настройки времени и часового пояса используется новое окно в приложении (Параметры/Settings). Вы можете установить часовой пояс из графического интерфейса, щелкнув правой кнопкой по значку часов в системном трее и выбрав пункт Adjust date/time (Настройка времени и даты). По умолчанию Windows пытается автоматически выбрать часовой пояс (включена опция Set time zone automatically/Автоматически устанавливать часовой пояс). Вы можете отключить эту опцию и задать нужный часовой пояс вручную, выбрав его в выпадающем списке.

Также вы можете вызвать классическое окно настройки времени в Windows, выполнив команду
timedate.cpl
.

  • Настройка часового пояса через GPO
  • Ошибка при изменении часового пояса в Windows Server 2019

Назначаем права на изменение часового пояса в Windows

По-умолчанию смена часового пояса в Windows 10 не требует от пользователя наличия прав администратора (в отличии от смены времени/даты). Вы можете запретить пользователям менять часовой пояс с помощью локальной политики безопасности (Local Security Settings
secpol.msc
). Интересующая нас настройка находится в разделе Security Settings -> Local Policy -> User Rights Assignment (Параметры безопасности -> Локальные политики -> Назначение прав пользователя). Политика называется Change the time zone (Изменение часового пояса). По умолчанию изменить часовой пояс в Windows 10 может сама система, администраторы и все пользователи. Чтобы запретить простым пользователям самим менять часовой пояс, необходимо удалить Users из списка учетных записей в этой политике.

Изменение часового пояса - политика

В Windows Server право на изменение часового пояса есть только у Local Service и администраторов.

Утилита TZUtil: изменить часовой пояса из командной строки Windows 10

Для смены часового пояса в Windows 11/10/8.1, Windows Server 2019/2016/2012 R2/ используется специальная утилита командной строки tzutil.exe (Windows Time Zone Utility), впервые появившаяся в Windows 7. Исполняемый файл утилиты хранится в каталоге
%WINDIR%System32
.

Разберемся с возможностями и особенностями использования утилиты TZUtil.

Откройте командную строку (
cmd.exe
). Чтобы узнать текущий часовой пояс и его идентификатор (TimeZoneID), выполните команду:

tzutil /g

В данном примере Russian Standard Time это идентификатор текущего часового пояса:

tzutil /g узнать текущий часовой пояс компьютера

Выведите список всех часовых поясов с их названием и идентификаторами:

Если вы хотите быстро найти вывести все доступные часовые пояса, например, со сдвигом UTC +2, выполните команду:

tzutil /l | find /I "utc+02"

поиск временных зон по UTC смещению

Чтобы изменить текущий часовой пояс (UTC+03:00) Москва, Санкт-Петербург, Волгоград – (Russian Standard Time) на (UTC+04:00) Ижевск, Самара (Russia Time Zone 3). Для этого нужно указать идентификатор часового пояса:

tzutil /s "Russia Time Zone 3"

tzutil /s задать часовой пояс Russia Time Zone

Текущий часовой пояс хранится в реестре Windows. Вы можете проверить, что он изменился так:

reg query HKLMSYSTEMCurrentControlSetControlTimeZoneInformation

настройки часового пояса в реестре

Чтобы отключить переход на летнее время для конкретного пояса, нужно указать идентификатор часового пояса с суффиксом _dstoff, например

tzutil /s “Pacific Standard Time_dstoff”

Эта команда изменит часовой пояс компьютера и отключите сезонный перевод часов.

Вы можете вывести полную информацию о часовом поясе и настройках сезонного перевод часов так:

w32tm /tz

Часовой пояс: Текущий:TIME_ZONE_ID_UNKNOWN Сдвиг: -180мин (UTC=LocalTime+Bias)
[Зимнее время:"RTZ 2 (зима)" Сдвиг:0мин Дата:(не указано)]
[Летнее время:"RTZ 2 (лето)" Сдвиг:-60мин Дата:(не указано)]

w32tm /tz

В Windows XP и Windows Server 2003 для смены часового пояса из командной строки нужно было использовать такие команды:

RunDLL32.exe shell32.dll,Control_RunDLL timedate.cpl,,/Z Russian Standard Time

Или:

Control.exe TIMEDATE.CPL,,/Z Russian Standard Time

Управление часовым поясом в Windows из PowerShell

Получить настройки текущего часового пояса можно и в консоли PowerShell. Используйте команду:

[TimeZoneInfo]::Local

Или

Get-TimeZone

Id                         : Ekaterinburg Standard Time
DisplayName                : (UTC+05:00) Екатеринбург
StandardName               : RTZ 4 (зима)
DaylightName               : RTZ 4 (лето)
BaseUtcOffset              : 05:00:00
SupportsDaylightSavingTime : True

powershell Get-TimeZone

В PowerShell вы можете просмотреть все возможные часовые пояса, доступные в Windows:

[System.TimeZoneInfo]::GetSystemTimeZones()

Или
Get-TimeZone -ListAvailable

Get-TimeZone -ListAvailable

Список часовых поясов довольно большой, чтобы найти название нужного часового пояса, воспользуйтесь фильтром:

Get-TimeZone -ListAvailable | Where-Object {$_.displayname -like "*Samara*"}

Или:

Get-TimeZone -ListAvailable | Where-Object {$_.Id -like "*Russ*"}

фильтр для часовых поясов в powershell

Можно вывести все часовые пояса в алфавитном порядке:

Get-TimeZone -ListAvailable | Select Id | Sort Id

Чтобы изменить текущий часовой пояс из PowerShell, выполните команду

Set-TimeZone -Name "Astrakhan Standard Time"

В этих примерах используется версия PowerShell 5.1, но они также работают и в более новых версиях.

Настройка часового пояса через GPO

Для централизованной настройки часового пояса на компьютерах в домене Active Directory вы можете использовать групповые политики. Готовой политики для настройки часового пояса в GPO нет. Чаще всего используются следующие два варианта настройки часового пояса через GPO: с помощью logon скрипта GPO и с помощью импорта настроек часового пояса в реестр.

Для задания часового пояса через логон скрипт GPO, можете использовать простейший PowerShell скрипт (подходит для всех версий Windows, вплоть до Windows XP и Windows Server 2003):

$tmZone = "Russian Standard Time"
$WinOSVerReg = Get-Item "HKLM:SOFTWAREMicrosoftWindows NTCurrentVersion"
$WinOSVer = $WinOSVerReg.GetValue("CurrentVersion")
if ($WinOSVer -GE 6){
tzutil.exe /s $tmZone
} Else {
$param = "/c Start `"Change tmZone`" /MIN %WINDIR%System32Control.exe TIMEDATE.CPL,,/Z "
$param += $tmZone
$proc = [System.Diagnostics.Process]::Start( "CMD.exe", $param )
}

Другой способ настроек времени заключается в импорте содержимого ветки HKLMSYSTEMCurrentControlSetControlTimeZoneInformation с эталонного компьютера с настроенным временем на другие компьютеры через GPO. Процедура импорта ветки реестра через Group Policy Preferences описана в этой статье.

Выберите эту ветку целиком с помощью Registry Browser. В результате все настройки временной зоны будут импортированы в раздел редактора GPO (Computer Configuration -> Preferences -> Windows Settings -> Registry).

In this article, we want to teach you How To Change the Time Zone on Windows Server 2019.

The term Time Zone can be used to describe several different things, but mostly it refers to the local time of a region or a country.

As you know, changing the Time Zone is important for people who use a variety of Windows services and provide that service on a network or Internet level.

In this guide, you will learn to change Time Zone with PowerShell.

Steps To Change Time Zone on Windows Server 2019 with PowerShell

To change the Time Zone with PowerShell, you need to open a PowerShell with Administrator access.

To do this, from your start menu type PowerShell and right-click on it, and select Run as an Administrator.

Check the Current Time Zone on Windows Server 2019

After you open your PowerShell on your Windows Server, run the following command to see your current Time Zone:

Get-TimeZone

In your output, you will see something similar to this:

Output
Id                         : Pacific Standard Time
DisplayName                : (UTC-08:00) Pacific Time (US & Canada)
StandardName               : Pacific Standard Time
DaylightName               : Pacific Daylight Time
BaseUtcOffset              : -08:00:00
SupportsDaylightSavingTime : True

List Available Time Zones on Windows Server 2019

Now you can use the following command to list the available Time Zones on your Windows Server:

Get-TimeZone -ListAvailable

In your output you will see:

Output
Id                         : Dateline Standard Time
DisplayName                : (UTC-12:00) International Date Line West
StandardName               : Dateline Standard Time
DaylightName               : Dateline Daylight Time
BaseUtcOffset              : -12:00:00
SupportsDaylightSavingTime : False

Id                         : UTC-11
DisplayName                : (UTC-11:00) Coordinated Universal Time-11
StandardName               : UTC-11
DaylightName               : UTC-11
BaseUtcOffset              : -11:00:00
SupportsDaylightSavingTime : False

Id                         : Aleutian Standard Time
DisplayName                : (UTC-10:00) Aleutian Islands
StandardName               : Aleutian Standard Time
DaylightName               : Aleutian Daylight Time
BaseUtcOffset              : -10:00:00
SupportsDaylightSavingTime : True
...

After viewing the list of available time zones and selecting the desired time zone, with the Set-TimeZone command you can set your Windows server time zone.

Set Time Zone

For example:

Set-TimeZone -Name “Canada Central Standard Time”

At this point, you can use the following command again to see your current Time Zone:

Get-TimeZone

In your output you will see that your Time Zone has been changed:

Output
Id                         : Canada Central Standard Time
DisplayName                : (UTC-06:00) Saskatchewan
StandardName               : Canada Central Standard Time
DaylightName               : Canada Central Daylight Time
BaseUtcOffset              : -06:00:00
SupportsDaylightSavingTime : False

Also, you can use different ways to change your Windows Time Zone like:

Change the Time Zone from the CMD, from the control panel, and from the setting.

Conclusion

At this point, you have successfully changed your Windows Server 2019 Time Zone.

Hope you enjoy it.
