Understanding Time and Date Settings in Windows
The importance of accurate timekeeping cannot be overstated. System time impacts various operations, from file timestamps to scheduled tasks. For instance, an incorrectly set time can lead to confusion in file versioning or disrupt automated scripts that rely on precise timing. Thus, understanding how to effectively manage system time is vital for any computer user.
Windows Time Services
The Windows Time service (w32time) is responsible for synchronizing the date and time on your computer with an external time source, typically via the Internet. This synchronization ensures that your system clock remains accurate, preventing time drift that can lead to broader system issues. Familiarizing yourself with this service is essential for maintaining the integrity of your time settings.

Рассмотрим ситуацию, когда вам необходимо синхронизировать время вашей Windows машине или Windows сервере с вашим NTP сервером, или внешне доступным сервером времени. Задача простая, но у новичков в системном администрировании это может вызвать некоторые трудности. Так давайте разберемся!
Небольшое отступление: синхронизировать время на всех узлах сети (сервера, рабочие станции, сетевое оборудование, sip телефоны и т.д.) с единым сервером времени является обязательным, для корректной работы всех служб и сервисов в корпоративной сети. Так, например, это необходимо для корректной работы служб Active Directory, контроллеров доменов, почтовых серверов, рабочих станций, обеспечения корректных прав доступа и безопасности.
Операционные системы семейства Windows содержат службу времени W32Time. Эта служба предназначена для синхронизации времени в пределах организации. W32Time отвечает за работу как клиентской, так и серверной части службы времени, причем один и тот же компьютер может быть одновременно и клиентом и сервером NTP (NTP — Network Time Protocol).
Для того чтобы синхронизировать ваш сервер или рабочую станцию вам необходимо выполнить следующие команды, в командной строке (CMD), запущенной от имени администратора:
1. w32tm /query /source – проверяем источник, на который настроена служба времени в данный момент. Вывод команды либо покажет нам имя или адрес существующего ntp сервера, или в случае его отсутствия выдаст “Free-running System Clock”.
2. w32tm /config /syncfromflags:manual /manualpeerlist:”source” – данной командой указываем источник эталонного времени (NTP Сервер) . Заменяем source на ip адрес или на FQDN. В доменной сети стоит указывать адрес контроллера домена. В случае правильности выполнения получим вывод “Команда выполнена успешно”.
3. w32tm /config /update – обновляем службу времени, чтобы новые настройки применились.
4. w32tm /resync – запускаем принудительное обновление с новым сервером времени.
Все. Вы синхронизировали службу времени на вашей машине с внешним источником. Данный подход позволит вам добиться того, что все машины в вашей сети будет иметь единое правильное время, что позволит избежать ряда сбоев из за расхождения во времени.
Дополнительные команды управления службой времени:
w32tm /query /source — выводит источник времени, на который настроена служба Windows Time
w32tm /monitor — при запуске на контроллере домена (КД) показывает, насколько отличается время на других КД и на внешнем источнике времени, на который настроен PDC
w32tm /config /syncfromflags:manual /manualpeerlist:ru.pool.ntp.org — настройка в качестве источника времени пула ntp-серверов ru.pool.ntp.org
w32tm /config /update — эту команду необходимо выполнить, чтобы служба времени применила новые настройки
w32tm /resync — выполнение синхронизации времени
w32tm /unregister — отменяет регистрацию службы и удаляет настройки из реестра
w32tm /register — регистрирует службу и восстанавливает настройки по умолчанию
Making sure the clock on your computer is correct might sound like a minor thing, but it’s actually very important for keeping your computer running well. This is also extremely important for businesses that need the right time stamps for log files, syncing data, and keeping things secure. In this guide, I’ll show you how to sync your Windows 11 clock with an internet time server, change your Network Time Protocol (NTP) server, and update your NTP time using the command prompt (CMD).

Why keeping time right on your PC is important
Having your computer’s clock synced isn’t just about the right time showing on your taskbar. It’s also very important for a bunch of other computer tasks like managing files, scheduling stuff, network authentication, and logging what’s happening. It makes sure everything works together correctly and in order, which is a big deal when your computer’s part of a network.
Windows 11, just like the ones before it, uses the Network Time Protocol (NTP) to keep its clock in line with external time servers. By default, it syncs with time.windows.com, but there are loads of other public NTP servers out there you can use instead of the default one.

How to sync your Windows 11 time with the internet using CMD
If you want to make sure your system’s time is correct, Windows 11 lets you sync it up with an internet time server. The following steps will show you how to do that using CMD:
- Start by opening the Command Prompt as an admin. Just search for “cmd” or “command prompt” in the Start menu, right-click on “Command Prompt” in the search results, and pick “Run as administrator” from the menu that pops up.
- With the Command Prompt window open, enter the following command:
w32tm /resync
- Hit the Enter key after you type in the command. If all goes well, you’ll see a message saying the command worked. This step gets your system’s clock in sync with the default internet time server.
This feature can also help sort out issues if your computer’s clock is running slow or fast, making sure your computer’s time is as accurate as possible.

How to switch your NTP time server in Windows 11
Normally, your Windows system will keep its clock synced with Microsoft’s time server (usually time.windows.com). But sometimes, you might need to sync with a different NTP server, such as when the default one isn’t reachable at the moment or you prefer using a local time server in your country. Follow the steps below to switch to your preferred NTP time server in Windows 11 using CMD:
- Start Command Prompt as admin, just like before.
- In the Command Prompt window, type in the following command to change the NTP server. Swap “time.nist.gov” with your chosen NTP server’s address:
w32tm /config /syncfromflags:manual /manualpeerlist:time.nist.gov
- Hit the Enter key after you enter the command. This changes your NTP server to the one you prefer.
- To make sure the changes take effect, type this command and press Enter:
w32tm /config /update
- Then, get your system’s clock synced up with the new NTP server by using the w32tm /resync command.
How to refresh your NTP time
Refreshing your NTP time in Windows is just a matter of making it resync. Just follow the steps in “How to sync your Windows 11 Clock using CMD” and run the “w32tm /resync” command to get your system clock updated or fixed whenever you need.
What to do if you run into time sync issues
Even if you follow the steps exactly, you might run into problems with the time sync process. Like, you might see an error when trying to use the w32tm /resync command. Common errors include messages like “The service has not been started (0x80070426)” or “The computer did not resync because the time service was shutting down.”
If that happens, try this command to restart the w32time service, which can often kick any time syncing issues to the curb in Windows 11 or 10:
net stop w32time
net start w32time
After the service is back up and running, give the time sync another go with the w32tm /resync command.
If restarting doesn’t smooth things over, consider unregistering and then re-registering the time service in Windows with these steps:
- First, start by unregistering the Windows Time Service with this command:
w32tm /unregister. - Then, stop the Windows Time Service using this command:
net stop w32time. - Next up, re-register the Windows Time Service with this command:
w32tm /register. - Finally, get the Windows Time Service going again with:
net start w32time.
Running through the above steps will unregister, stop, re-register, and then restart the Windows Time Service. It should be able to fix any related issues in the process.
So, what have we learned?
Using the command line lets you set up automatic tasks, which is very helpful if you’re managing several computers—think network administrators, for example. You can write scripts that run these commands automatically at set times. Besides, since you can run CMD commands remotely, it’s also a handy option for network environments.

Every desktop computer keeps the correct time even when it is turned off by using a simple 3V Lithium battery cell (CR2032). But this is not a rechargeable battery cell, so it stops working after a year or so. You can easily replace this cell, but after replacing the cell, you have to update the time using the NTP servers so that your Windows PC keeps the accurate time. You can update the time using Windows graphical user interface and also through a command line interface (CLI). The CLI method works even when the time service is not properly configured in Windows.
Here is how you can sync time with NTP servers in Windows using the command line interface:
- Open an elevated command prompt. In Windows 8 and later versions, you can press the hotkey Win+X and choose Command Prompt (Admin) from the menu that shoes up. For earlier versions of Windows, you can search our side about opening elevated command prompt in Windows.
- In the elevated command prompt window, type the following commands. At the end of each line, press Enter to issue that command:
w32tm /register
sc start W32Time
w32tm /config /update /manualpeerlist:”pool.ntp.org”
- These commands will register Windows Time service if it is not registered for some reason, start this service, change the time server to “pool.ntp.org” and finally sync the computer time with the NTP server. Obviously, instead of “pool.ntp.org”, you can change the time server to any time server of your choice.>
You can also download update-time-windows.zip, extract the contents to Windows desktop, right-click on update-time-windows.cmd and choose Run as administrator. This will automatically run a batch file containing all the necessary commands for syncing the time.
Conclusion: Using command line interface or a batch file to sync the Windows PC time with a remote NTP server can be useful when you have to update it frequently. The reasons for frequent syncing could be a failing battery or dual boot operating systems having different time zones set.

Всем привет! Сегодня я расскажу, как синхронизация времени с контроллером домена, чтобы компьютеры нормально работали с AD. Если время у разных компьютеров будет отличаться хотя бы на 5 минут, то могут возникнуть проблемы с работой некоторых программных модулей.

Через параметры
Вообще вам необязательно делать синхронизацию через команду строку или любым другим способом, так как операционная система Windows сама это делает, если у вас правильно настроен домен синхронизации. Давайте проверим это:
Читаем – чем Виндовс 11 лучше 10-ой версии.
- Перейдите в «Параметры» через меню «Пуск».
- Найдите раздел «Время и язык».
- В первом разделе слева, в правом блоке можно просто нажать «Синхронизировать». Выше также будет отображаться сервер времени, который используется в данный момент.
Обратите внимание также, чтобы был правильно установлен «Часовой пояс». Галочку установки автоматического времени лучше включить, но вот пояс лучше ставить вручную. Дата аналогично ставится исходя из сервера.
Синхронизация с помощью командной строки
Также есть дополнительные команды для работы с w32tm. На официальном сайте Microsoft сказано, что устаревшие команды «Net time» – использовать не рекомендуется. Вместо этого используем w32tm и дополнительными атрибуты. Напишу пару примеров.
w32tm /query /source – выводит текущий сервер, с которого идет синхронизация.
w32tm /config /syncfromflags:manual /manualpeerlist: “АДРЕС_СЕРВЕРА” – принудительно указать адрес сервера, с которым будет идти синхронизация времени.
w32tm /config /update – обновляет конфигурационный файл времени.
w32tm /resync /rediscover – выполнить синхронизацию прямо сейчас.
Чтобы синхронизировать время с сервером делаем следующее:
w32tm /query /configuration
Проверяем чтобы в строке «Type» было значение «NT5DS» – это значит, что синхронизация идет с помощью домена AD. Если у вас не так и стоит NTP (локальная синхронизация), то сбрасываем настройки до NT5DS:
w32tm /config /syncfromflags:domhier /update net stop w32time && net start w32time
После этого система сама найдет домен с сервером в иерархии AD и подключиться к нему. Если подключиться не получается. То прописываем команду отмены регистрации и удаления конфига:
w32tm /unregister
Восстанавливаем конфигурацию обратно, как было в настройках:
w32tm /register
Синхронизируем время обратно с Active Directory:
w32tm /config /syncfromflags:domhier /update
Службу теперь надо перезагрузить:
net stop w32time && net start w32time
Апгрейдим настройки:
w32tm /config /update
И теперь можно синхронизировать само время:
w32tm /resync
Проверьте, чтобы служба была запущена и сервер правильно определился:
w32tm /query /status
Основная проблема – это ошибка, что служба не запущена. В таком случае зайдите в «Службы» операционной системы, найдите «Службу времени Windows» и запустите её вручную. После этого уже можно вводить команды дальше. До новых встреч на портале WiFiGiD.RU.
