Windows中不正确的时钟可能会导致系统范围的异常并破坏依赖 Internet 连接的应用程序。我们将向您展示如何再次将其设置为正确的日期和时间。
默认情况下，Windows使系统时钟与 Microsoft 的时间服务器保持同步。如果失败，您必须手动更改时间和日期或强制将时钟与本地时间服务器同步。本教程将帮助您了解如何在Windows 11和 10 中更改时间、日期和区域。
在Windows中手动更改时间(Change Time)和日期(Date)
Windows中的默认日期和时间配置使系统时间与 Internet 时间服务器保持同步。在不同时区之间旅行时，它还可以使用位置服务来设置您的区域。但是，如果时钟不正确或者您出于其他原因想要提前或回滚时钟，您始终可以手动调整时间、日期和地区。
1. 右键单击任务栏上的时钟(Clock)并选择调整(Adjust)日期和时间。或者，打开开始(Start)菜单并选择Settings > Time和语言 >日期(Date)和时间。
2. 在启动的设置窗口中，禁用自动(Settings)设置(Set)时间旁边的开关。此外，关闭自动设置(Set)时区设置（如果激活）。
3. 选择时(Time)区旁边的下拉菜单并设置正确的区域。
4. 选择手动设置(Set)日期和时间
旁边的更改按钮。(Change)
5. 根据需要调整日期(Date)和时间(Time)字段，然后选择更改(Change)。
注意：如果您居住在实行夏令时的地区，如果您不介意自己进行调整，则可以禁用自动调整(Adjust)夏令时设置。
在Windows中自动设置时间(Set Time)和日期(Date)
尽管可以自行设置时间和日期，但让Windows将日期和时间与 Internet 时间服务器同步是确保系统时钟准确性的最佳方式。当自动时间同步失败时，以下操作可能会使其再次工作。
1. 右键单击任务栏上的时钟(Clock)并选择调整(Adjust)日期和时间。
2.禁用自动设置(Set)时间旁边的开关。然后，等待几秒钟，然后再次打开它。这应该会提示Windows再次拉出正确的时间。
注意：如果时区总是显示不正确，请确保禁用自动设置(Set)时区旁边的开关，手动选择您所在的地区，然后关闭自动设置(Set)时区，然后再打开。
3. 如果问题仍然存在，请向下滚动到其他(Additional)设置 ( Windows 11 ) 或同步(Sync)您的时钟 ( Windows 10 )，然后选择立即同步(Sync)按钮，这将强制将时间和日期与 Microsoft 的时间服务器同步。
更改 Windows 日期和时间(Time)的其他方法(Ways)
您有几种替代方法可以更改 PC 上的时间和日期。一种方法涉及传统的日期(Date)和时间(Time) 控制面板(Control Panel)小程序，另一种方法是基于命令提示符(Command Prompt)的。如果您无法访问 Windows 中的“设置”应用程序，(trouble accessing the Settings app in Windows)请使用它们。
日期和时间小程序
您可以手动或使用日期(Date)和时间(Time)小程序自动设置 PC 时间和日期。要访问和使用它：
1. 按Windows Key + R，键入 timedate.cpl，然后按Enter。
2. 使用更改(Change)日期和时间以及更改(Change)时区按钮设置正确的日期和时间。
3. 选择日期(Date)和时间(Time)窗口顶部的Internet 时间选项卡，然后选择(Internet Time)更改(Change)设置。如果您希望 Windows 自动设置正确的时间，请确保与Internet时间服务器同步旁边的框处于活动状态。
注意：如果 Microsoft 的时间服务器总是设置错误的时间，请打开Server(Server)旁边的菜单，从National Institute of Standards and Technology -time.nist.gov 中选择服务器，然后(Technology—time.nist.gov—and)选择立即更新(Update)。
命令提示符控制台
令人惊讶的是，使用命令提示符(Command Prompt)控制台设置时间和日期相对简单。要做到这一点：
1. 打开开始(Start)菜单，输入 cmd，然后选择以管理员身份
运行。(Run)
2. 在用户帐户控制(User Account Control)弹出窗口中选择是。
3. 输入时间并按Enter。然后，以 hh:mm:ss.ms 格式输入正确的时间，然后按Enter。接下来(Next)，运行 date 命令并以 mm-dd-yy 格式设置正确的日期。
注意：如果您想阻止Windows之后调整您的更改，请
通过“设置”(Settings)应用程序或“日期(Date)和时间”(Time)小程序禁用自动时间同步。
正确的时间和日期很重要
许多Windows问题源于错误地设置时间和日期，因此请不要忘记手动调整或定期强制同步时钟与 Microsoft 的时间服务器。即使您有意更改时间和日期（例如让旧程序运行或加快视频游戏中的游戏时钟），最好在完成后快速更改。
但是，如果Windows中的时间和日期仍然出现错误，可能是由于多种原因。例如，您可能正在处理恶意软件感染、过时的操作系统或BIOS/UEFI或没电的CMOS电池。查看我们在 Windows 中修复系统时钟的完整指南以(complete guide to fixing the system clock in Windows)解决问题。
How to Change the Time and Date in Windows
An incorrect clock in Windows can lead to system-wide anomalies and break aрps that rely on internet сonnectivity. We will show you how to set it to the correct date and time again.
By default, Windows keeps the system clock in sync with Microsoft’s time servers. If that fails, you must manually change the time and date or forcibly synchronize the clock with a local time server. This tutorial will help you learn how to change the time, date, and region in Windows 11 and 10.
Manually Change Time and Date in Windows
The default date and time configuration in Windows keep the system time in sync with an internet time server. It could also use location services to set your region when traveling between different time zones. However, you can always manually adjust the time, date, and region if the clock is incorrect or you want to advance or roll back it for another reason.
1. Right-click the Clock on the taskbar and select Adjust date and time. Or, open the Start menu and select Settings > Time & language > Date & time.
2. On the Settings window that launches, disable the switch next to Set time automatically. Also, turn off the Set time zone automatically setting (if active).
3. Select the drop-down menu next to Time zone and set the correct region.
4. Select the Change button next to Set date and time manually.
5. Adjust the Date and Time fields as needed and select Change.
Note: If you live in a region with daylight savings time, you can disable the Adjust for daylight saving time automatically setting if you don’t mind making the adjustments yourself.
Automatically Set Time and Date in Windows
Despite being able to set the time and date on your own, letting Windows sync the date and time with an internet time server is the best way to ensure the accuracy of the system clock. When automatic time-syncing fails, the following actions might get it working again.
1. Right-click the Clock on the taskbar and select Adjust date and time.
2. Disable the switch next to Set time automatically. Then, wait for a couple of seconds and turn it on again. That should prompt Windows to pull the correct time again.
Note: If the time zone always appears incorrectly, make sure to disable the switch next to Set time zone automatically, select your region manually, and then toggle the Set time zone automatically switch off, then on.
3. If the issue persists, scroll down to Additional settings (Windows 11) or Synchronize your clock (Windows 10) and select the Sync now button That will forcibly sync the time and date with Microsoft’s time server.
Other Ways to Change Windows’ Date and Time
You’ve got a couple of alternative ways to change the time and date on your PC. One method involves the traditional Date and Time Control Panel applet, and the other is Command Prompt-based. Use them if you have trouble accessing the Settings app in Windows.
Date and Time Applet
You can set the PC time and date manually or automatically using the Date and Time applet. To access and use it:
1. Press Windows Key + R, type timedate.cpl, and press Enter.
2. Use the Change date and time and Change time zone buttons to set the correct date and time.
3. Select the Internet Time tab on the top of the Date and Time window and select Change settings. If you want Windows to set the correct time automatically, make sure that the box next to Synchronize with an Internet time server is active.
Note: If Microsoft’s time server always sets the wrong time, open the menu next to Server, select the server from the National Institute of Standards and Technology—time.nist.gov—and select Update now.
Command Prompt Console
Surprisingly, setting the time and date using the Command Prompt console is relatively straightforward. To do that:
1. Open the Start menu, type cmd, and select Run as administrator.
2. Select Yes on the User Account Control pop-up.
3. Type time and press Enter. Then, enter the correct time in the hh:mm:ss.ms format and press Enter. Next, run the date command and set the correct date in the mm-dd-yy format.
Note: Disable automatic time-syncing via the Settings app or the Date and Time applet if you want to prevent Windows from adjusting your changes afterward.
The Correct Time and Date Matters
Many Windows issues stem from incorrectly setting the time and date, so don’t forget to manually adjust or force-sync the clock periodically with Microsoft’s time servers. Even if you intentionally change the time and date (such as to get an old program to work or speed up the in-game clock in a video game), it’s best to change that back quickly once you’re done.
However, if the time and date in Windows continue to appear wrong, it could be due to several reasons. For example, you might be dealing with a malware infection, an outdated operating system or BIOS/UEFI, or a dead CMOS battery.
