默认情况下， Windows 11/10/8/7每周将您的系统时间与Internet服务器同步。如果您想手动同步和更新您的系统时间与像time.windows,com这样的^{(time.windows,com)}Internet 时间^{(Internet Time)}服务器，您必须右键单击任务栏中的时间^(Time)> Adjust Time和日期 > Internet 时间^{(Internet Time)}选项卡> Change设置>立即> Update.

更改Windows Internet 时间更新间隔^{(Windows Internet Time Update Interval)}

但是，如果您想更频繁地与服务器自动同步时间怎么办——比如每天？您可能有理由希望将其更改为每天 - 甚至每月！让我们看看你是怎么做到的。在继续之前，让我们了解一些有关时间同步在Windows上的工作原理的知识。

Windows 时间服务 – W32Time.exe

The Windows Time Service or W32Time.exe maintains date and time synchronization on all clients and servers in the network. If this service is stopped, date and time synchronization will be unavailable. If this service is disabled, any services that explicitly depend on it will fail to start.

Windows 时间^{(Windows Time)}服务的许多注册表^(Registry)项与同名的组策略^{(Group Policy)}设置相同。组策略^{(Group Policy)}设置对应于位于以下位置的同名注册表项：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\

Windows 时间服务工具 – W32tm.exe^{(Windows Time Service Tool – W32tm.exe)}

W32tm.exe或Windows 时间服务工具^{(Windows Time Service Tool)}可用于配置Windows 时间服务^{(Windows Time Service)}设置。它还可用于诊断时间服务的问题。W32tm.exe是用于配置、监视或排除Windows 时间^{(Windows Time)}服务故障的首选命令行工具。TechNet 对此进行了更多说明。

要使用此工具，您必须打开提升的命令提示符^{(elevated command prompt)}，键入W32tm /?并按Enter以获取其所有参数的列表。当w32tm /resync运行时，它告诉计算机立即同步其时钟。当我运行此命令时，我收到以下错误：服务尚未启动^{(The service has not been started)}。因此，必须启动Windows 时间服务^{(Windows Time service)}才能使其正常工作。

1]使用任务计划程序

现在，如果您要使用任务计划程序^{(Task Scheduler)}创建任务，每天运行Windows 时间服务和此同步命令，作为具有最高权限的^{(Windows Time Service)}本地服务^{(Local Service)}，您将能够让您的Windows计算机每隔天。

您必须打开任务计划程序^{(Task Scheduler)}并导航到Task Scheduler Library > Microsoft > Windows > Time Synchronization。现在您必须单击Create Task...链接来创建任务。这篇文章将详细告诉您 如何使用 Task Scheduler 来安排任务^{(how to schedule a task using Task Scheduler)}。

在Actions下，您必须选择Start a program %windir%\system32\sc.exe with arguments start w32time task_started。这将确保Windows 时间^{(Windows Time)}服务正在运行。然后，您可以将第二个操作设置为使用参数  /resync启动程序^{(Start a program)} %windir%\system32\w32tm.exe。您可以根据个人喜好选择其他设置。

提示^(TIP)：您还可以使用tzutil.exe更改时区^{(Time Zone)}。

2]使用注册表编辑器

您还可以查看这是否适合您。打开Windows 注册表编辑器^{(Windows Registry Editor)}并导航到以下注册表项：

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet\Services \W32Time\TimeProviders\NtpClient

选择特殊轮询间隔。^{(SpecialPollInterval.)}

This SpecialPollInterval entry specifies the special poll interval in seconds for manual peers. When the SpecialInterval 0x1 flag is enabled, W32Time uses this poll interval instead of a poll interval determined by the operating system. The default value on domain members is 3600.

独立客户端和服务器上的默认值为604,800。604800 秒是 7 天。因此，您可以将此十进制值^{(decimal value)}更改为 86400，使其每 24 小时同步一次。

There is also the easy way out!

这个来自DougKnox.com的免费软件工具可让您将Internet 时间更新^{(Internet Time Update)}间隔从每周^(Weekly)更改为每天^(Daily)或每小时^(Hourly)。您必须以管理员身份运行该工具。

这个便携式工具适用于Windows XP、Windows Vista、Windows 7和Windows 8。未检查它是否适用于Windows 11/10。

如果您的时间同步^{(Time Synchronization)}失败并出现错误 - Windows 时间服务不工作^{(Windows Time Service not working)(Windows Time Service not working)}，这篇文章将为您提供帮助。

Change Internet Time Update interval in Windows 11/10

By default Windows 11/10/8/7 syncs your system time with Internet serνers on a weеkly basis. If you want tо manually sync and update your system time with an Internet Time server like time.windows,com, you have to right-click on the Time in the taskbar > Adjust Time & date > Internet Time tab > Change settings > Update now.

Change Windows Internet Time Update Interval

But what if you want to sync your time automatically, with the servers more frequently – like say daily? You may have your reasons for wanting to change this to daily – or even on a monthly basis! Let us see how you can do it. Before we proceed, let’s learn a few things about how Time synchronization works on Windows.

Windows Time Service – W32Time.exe

The Windows Time Service or W32Time.exe maintains date and time synchronization on all clients and servers in the network. If this service is stopped, date and time synchronization will be unavailable. If this service is disabled, any services that explicitly depend on it will fail to start.

Many Registry entries for the Windows Time service are the same as the Group Policy setting of the same name. The Group Policy settings correspond to the registry entries of the same name located in:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\

Windows Time Service Tool – W32tm.exe

W32tm.exe or the Windows Time Service Tool can be used to configure Windows Time Service settings. It can also be used to diagnose problems with the time service. W32tm.exe is the preferred command-line tool for configuring, monitoring, or troubleshooting the Windows Time service. TechNet throws more light on this.

To use this tool, you will have to open an elevated command prompt, type W32tm /? and hit Enter to get the list of all its parameters. When w32tm /resync is run, it tells the computer to synchronize its clock right away. When I ran this command I received the following error: The service has not been started. So the Windows Time service has to be started for this to work.

1] Using  Task Scheduler

Now if you were to create a task using the Task Scheduler, to run the Windows Time Service and this sync command on a daily basis, as a Local Service with highest privileges, you would be able to make your Windows computer synchronize your system time every day.

You will have to open the Task Scheduler and navigate to Task Scheduler Library > Microsoft > Windows > Time Synchronization. Now you will have to click on the Create Task… link to create the task. This post will tell you in detail how to schedule a task using Task Scheduler.

Under Actions, you would have to choose Start a program %windir%\system32\sc.exe with arguments start w32time task_started. This will ensure that the Windows Time service is running. You may then set the second action to Start a program %windir%\system32\w32tm.exe with the argument  /resync. The other settings you may choose as per your personal preferences.

TIP: You can also change Time Zone with tzutil.exe.

2] Using Registry Editor

You can also see if this works for you. Open Windows Registry Editor and navigate to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet\Services \W32Time\TimeProviders\NtpClient

Select SpecialPollInterval.

This SpecialPollInterval entry specifies the special poll interval in seconds for manual peers. When the SpecialInterval 0x1 flag is enabled, W32Time uses this poll interval instead of a poll interval determined by the operating system. The default value on domain members is 3600.

The default value on stand-alone clients and servers is 604,800. 604800 seconds is 7 days. So you may change this decimal value to 86400 to make it sync every 24 hours.

There is also the easy way out!

This freeware tool from DougKnox.com lets you change the Internet Time Update interval from Weekly to Daily or Hourly. You will have to run the tool as an administrator.

This portable tool works on Windows XP, Windows Vista, Windows 7 & Windows 8. Not checked if it works on Windows 11/10.
