如果您的Windows未正确同步系统时间，请使用这些免费软件强制Windows在每次启动时同步时间。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。它做得很好。但是也有用户反映时间同步失败(Time Synchronization fails)是因为Windows 时间服务(Windows Time Service)没有工作，或者Windows 系统时间向后跳。如果您遇到这个问题，您可以考虑在您的Windows系统上使用免费的时间(Time)同步软件。
PC免费时间同步软件(Time)
与您的计算机的时间同步问题可能是由于某些更改的设置或第三方软件的干扰或由于CMOS电池故障或其他硬件问题造成的。当Windows无法正确同步您的系统时间时，这可能会导致您每次打开计算机时都显示错误的日期和时间——这可能会导致一些计算或浏览问题。为了解决这个问题，我们有很多第三方时间同步软件可以从互联网上更新您的系统时间。
1]网络时间或网络时间
NetTime是一个免费的开源工具，适用于简单网络时间协议(Simple Network Time Protocol)( SNTP )。要开始使用此工具，您只需要与您的系统时间同步的时间服务器的地址。虽然，该工具预装了默认的NetTime时间服务器，但显然我的计算机无法连接到其中的一些服务器。通过指定IP 地址(IP Address)或主机名(Hostname)，您最多可以添加五个时间(Time)服务器。
NetTime支持通过三种协议进行通信，即SNTP、TCP和UDP。因此，您可以根据您的时间服务器选择协议。该工具旨在自动保持系统时间同步。因此，一旦您配置了该工具，它将在后台自动同步时间。您还可以强制同步时间或指定应再次同步时间的时间间隔。您可以根据要求自定义其他一些设置。单击(Click) 此处(here)下载 NetTime。
2]原子时钟同步
原子钟被认为是有史以来最精确的时钟。这些设备是国际时间分配服务的标准。这些服务随后用于电视广播、卫星等。如果您想将计算机的时间与原子钟的时间同步，那么您可能会对Atomic Clock Sync感兴趣。
此工具可帮助您将计算机时间与美国(United)国家(National Institute)标准(Standards)与技术研究院(Technology)( NIST )(NIST)维护的原子时间服务器同步。(States)这些服务器提供的时间被认为是最准确和正确的。您可以指定同步间隔，也可以随时强制同步。可用的自定义功能不多，但该工具确实带有一个修复实用程序，如果出现任何问题，它可以帮助您修复Windows 时间服务。(Windows Time Service)单击此处(here)下载原子钟同步。
3] 尺寸 4
Dimension 4是另一个可用于Windows的时间同步工具。它的工作方式有点类似于NetTime。我最喜欢Dimension 4的地方是内置的全球时间服务器列表。该工具带有一个内置的时间服务器列表及其位置。因此，您无需在线搜索时间服务器。Dimension 4具有所有高级和基本功能，可让Windows时间与最佳时间服务器保持同步。单击(Click) 此处(here)下载维度 4。
这些工具可以帮助您使计算机的时间与国际服务器保持同步。你使用任何其他工具吗？如果是这样，请告诉我们。
Best free Time synchronization software for Windows 11/10
If your Windows is not synchronizing system time corrеctly, use these freeware to force Windows to sync time аt every startup. By default Wіndows 11/10/8/7 syncs your system time with Internet servers on a weekly baѕis. And it does the јob well. Bυt there are users who report that the Time Synchronization fails because Windows Time Service was not working, or that Windows System Time jumps backward. If you face this issue, you can consider using free Time synchronization software on your Windows system.
Free Time synchronization software for PC
This time synchronization issues with your computer may be caused due to some changed settings or the interference dues to a 3rd-party software or due to a faulty CMOS battery or other hardware issues. When Windows fails to synchronize your system time correctly, this might result in the wrong date and time being displayed every time you turn on your computer – and that could cause several computing or browsing problems. To fix this issue, we have a lot of third-party time synchronization software that can update your system time from the internet.
1] NetTime or Network Time
NetTime is a free open source tool that works upon the Simple Network Time Protocol (SNTP). To get started with this tool, all you need is the address of time servers you want to synchronize your system time with. Although, the tool comes preloaded with the default NetTime time servers apparently my computer was unable to connect to some of them. You can add up to five Time servers by specifying their IP Address or Hostname.
NetTime supports communication over three protocols, namely SNTP, TCP, and UDP. So you can choose the protocol as per your time server. The tool is designed to automatically keep the system time in sync. So once you’ve configured the tool, it will automatically sync the time in the background. You can also force sync the time or specify the interval after which the time should be synced again. There are few other settings that you can customize as per the requirement.

2] Atomic Clock Sync
Atomic clocks are considered to be the most precise clocks ever built. These devices are standard for international time distribution services. These services are then used in television broadcasts, satellites, etc. If you ever wanted to sync your computer’s time to an atomic clock’s time, then you might be interested in Atomic Clock Sync.
This tool can help you sync your computer’s time with the atomic time servers maintained by the National Institute of Standards and Technology (NIST) in the United States. The time provided by these servers is considered to be the most accurate and correct. You can specify a synchronization interval and also force synchronize at any time. Not many customization features are available, but the tool does come with a repair utility that can help you fix Windows Time Service if anything goes wrong.

3] Dimension 4
Dimension 4 is yet another time synchronization tool available for Windows. It works in a way somewhat similar to NetTime. The thing I liked the most about Dimension 4 was the inbuilt list of worldwide time servers. The tool comes with a built-in list of time servers with their location. So you need not search for time servers online. Dimension 4 comes with all the advanced and basic features to keep Windows time in sync with the best time servers. Click here to download Dimension 4.
These were some of the tools that can help you keep your computer’s time in sync with the international servers. Do you use any other tool? If so, let us know.
