Clock is Not Updating Automatically in Windows 11/10

A clock that does not update automatically in Windows 11 or Windows 10 can lead to login issues, website certificate errors, failed updates, and problems with various applications. Fortunately, the issue is usually caused by incorrect settings rather than serious hardware failure.

Start by enabling Set time automatically, selecting the correct time zone, and using the Sync now option. If that does not work, restart the Windows Time service, synchronize using the Control Panel, reset the service with Command Prompt commands, and verify that your internet connection is stable. If the clock keeps resetting after every shutdown, inspect the CMOS battery. Finally, keep Windows updated to ensure you have the latest reliability improvements.

Let’s learn the possible causes and all the fixes in detail!

Why Does My Clock Appear Wrong on Windows 11/10?

There are several reasons why your Windows clock may stop updating automatically.

One of the most common causes is that automatic time synchronization has been turned off accidentally. Without this feature enabled, Windows cannot check Internet time servers to keep your clock accurate.

Another possible reason is an incorrect time zone. Even if the clock itself is accurate, selecting the wrong time zone can make your displayed time appear incorrect by several hours.

Sometimes, the Windows Time service may stop running or become disabled. This background service is responsible for synchronizing your computer’s clock with trusted Internet time servers.

Internet connectivity can also affect automatic synchronization. If your PC cannot reach Microsoft’s time server or another configured NTP (Network Time Protocol) server, the clock cannot update.

In older desktop and laptop computers, a weak or dead CMOS battery may cause the BIOS clock to reset every time the computer is powered off, causing Windows to display the wrong time after each startup.

Corrupted system files, outdated Windows updates, or incorrect registry settings can also interfere with automatic time synchronization.

Fortunately, most of these issues can be fixed within a few minutes.

Clock Is Not Updating Automatically in Windows 11/10 [Easy Fixes]

Clock is Not Updating Automatically in Windows 11 or 10

1: Turn On Automatic Date and Time

The first thing to check is whether Windows is allowed to set the date and time automatically.

Open the Settings app by pressing Windows + I on your keyboard. Select Time & language, then open Date & time.

Look for the option called Set time automatically. If it is turned off, switch it on. Also, enable Set time zone automatically if your device supports automatic location detection.

After enabling these settings, scroll slightly downward and click the Sync now button under Additional settings. Windows will immediately attempt to contact an Internet time server and update your clock.

Wait a few seconds and check whether the displayed time changes. In many cases, this simple step resolves the issue immediately.

2: Check That the Correct Time Zone Is Selected

Even if your clock is updating correctly, choosing the wrong time zone will make the displayed time inaccurate.

Open Settings, select Time & language, and then choose Date & time.

Locate the Time zone setting. Verify that it matches your current geographical location. If you recently traveled or moved to another region, Windows may still be using your previous time zone.

Select the correct time zone from the drop-down menu. After changing it, click Sync now again to refresh the system clock.

If the displayed time immediately becomes correct, the problem was simply an incorrect time zone rather than a synchronization issue.

3: Restart the Windows Time Service

Windows relies on the Windows Time service to synchronize your clock with Internet time servers.

Press Windows + R, type services.msc, and press Enter. The Services window will appear with a list of background services running on your computer.

Scroll until you find Windows Time. Double-click the service to open its properties. If the service status says Stopped, click Start.

Make sure Startup type is set to Automatic. Click Apply, then click OK.

Restart your computer after making these changes and see if your clock updates automatically.

If this service is disabled, Windows cannot keep your system time synchronized, regardless of your settings.

4: Manually Synchronize the Clock

Sometimes Windows simply needs a manual synchronization before automatic updates begin working again.

Open Settings, go to Time & language, and select Date & time. Scroll to the Additional settings section. Click Sync now.

Windows will contact its configured Internet time server and attempt to update the clock immediately.

If synchronization succeeds, you should see a confirmation message indicating that your clock was successfully synchronized.

If an error appears instead, continue to the next solution.

5: Synchronize Using Control Panel

Older Windows synchronization settings are still available through the Control Panel.

Open the Control Panel and change the view to Large icons.
Select Date and Time.
Open the Internet Time tab.
Click Change settings.
Make sure Synchronize with an Internet time server is checked.
Choose time.windows.com from the server list.
Click Update now.

If synchronization completes successfully, click OK to save your changes.

This method often fixes synchronization problems that the newer Settings app cannot resolve.

6: Run Windows Time Commands

If the Windows Time service is not responding correctly, resetting it through Command Prompt can help.

Open Command Prompt as an administrator.
Type the following command and press Enter: net stop w32time
Next, type: net start w32time
Finally, type: w32tm /resync
Press Enter after each command.

These commands restart the Windows Time service and force an immediate synchronization with the configured time server.

Restart your computer afterward and verify whether the issue has been resolved.

7: Check Your Internet Connection

Automatic clock synchronization depends on internet access.

If your network connection is unstable or disconnected, Windows cannot communicate with Internet time servers.

Open your web browser and visit a few websites to confirm that your internet connection is working properly.

If you are using a company, school, or public network, some network administrators block access to Internet time servers.

Connecting to another Wi-Fi network or restarting your router may resolve temporary connectivity issues.

Once your internet connection is stable, try synchronizing the clock again.

8: Check the CMOS Battery

If your computer loses the correct date and time every time it is turned off, the problem may not be Windows at all.

Desktop and laptop motherboards contain a small CMOS battery that keeps the BIOS clock running while the computer is powered off.

When this battery becomes weak, the system clock resets after every shutdown.

If your clock frequently returns to an old date or incorrect time after restarting your computer, replacing the CMOS battery may permanently solve the issue.

On desktop computers, replacing the battery is usually straightforward. On many laptops, accessing the battery may require partial disassembly, so you may prefer professional assistance if you are unfamiliar with computer hardware.

9: Install the Latest Windows Updates

Microsoft regularly releases updates that improve Windows reliability and fix known bugs.

Open Settings and select Windows Update. Click Check for updates. Download and install any available updates.

Restart your computer after installation completes.

If the clock synchronization problem was caused by a software bug, installing the latest updates may resolve it automatically.

FAQs

Why is my Windows clock always behind?

This usually happens because automatic time synchronization is disabled, the Windows Time service is not running, the wrong time zone is selected, or your computer has a failing CMOS battery.

Why won’t Windows sync my clock?

Windows may fail to synchronize if there is no internet connection, the configured time server is unavailable, the Windows Time service is disabled, or network restrictions are blocking access to internet time servers.

Does restarting the computer fix clock synchronization issues?

Sometimes it does. Restarting reloads Windows services, including the Windows Time service, which may restore automatic synchronization if the problem was temporary.

Can the BIOS affect Windows time?

Yes. Windows reads the hardware clock from your computer’s BIOS during startup. If the BIOS clock is incorrect because of a weak CMOS battery or incorrect BIOS settings, Windows may also display the wrong time.

Is it safe to manually change the date and time?

Yes. However, it is generally better to enable automatic date and time so Windows can maintain accurate synchronization without requiring manual adjustments.
