How To Reset Network Time Synchronization In Windows 11 Date And Time Settings
Network time synchronization in Windows 11 is a built-in feature that connects your PC to an online time server to keep your computer clock exact. Every 7 days by default, Windows talks to time.windows.com to fix any clock drift and match the official time.
When this background service breaks, your clock starts running fast or slow, which can stop websites from loading and break app logins. A quick reset fixes this problem by restarting the time service and forcing your PC to grab the correct time right now.
Open Settings , select Time & language, and click Date & time. Turn off the switch for Set time automatically, wait a moment, and turn it back on to reset your network time synchronization in Windows 11 Date And Time Settings. Your clock will update to the correct time.
Common Signs That Your Time Synchronization Is Broken
Common signs that your time synchronization is broken in Windows 11 include a taskbar clock that does not match your phone or wall clock, along with sudden security warnings when you try to open popular websites. These errors happen because your computer’s time does not match the security certificates required by modern web browsers, which blocks safe browsing until you fix the clock.
An incorrect taskbar clock compared to your phone or wall clock serves as the most obvious sign of a time synchronization problem in Windows 11 Date And Time Settings. You might also notice that web browsers show sudden security warnings when you try to visit popular websites. These browser security warnings happen because secure websites rely on exact time matching to keep your data safe. If your computer thinks it is in the past or future, it blocks you from visiting secure pages.

You might also notice problems with online games, chat apps, or file-sharing tools. If your messages appear out of order, or if your games disconnect with server errors, an inaccurate clock is often the hidden cause.
How to Check Your Current Date and Time Settings
Checking your current date and time settings in Windows 11 lets you see if your computer is updating the clock automatically or stuck on manual mode. You can view these details by opening the Windows Settings menu, going to the time and language section, and looking at the main clock configuration panel to see what needs to be changed.
- Click on the Start button at the bottom of your screen and select the Settings gear icon, or press the Windows key and the letter I on your keyboard at the same time.
- In the Settings window, click on Time & language on the left-hand menu.

Settings › Time & language - On the right side of the screen, click on Date & time.
Look for the option labeled Set time automatically. If this switch is turned off, your computer is not checking the internet for the correct time. If the switch is on, but your clock is still wrong, the automatic connection to the time server is stuck or failing.

How to Reset Network Time Synchronization in 🪟 Windows 11 Date And Time Settings
How to reset network time synchronization in Windows 11 Date And Time Settings is simple when your clock starts drifting. You can force your computer to sync with the official time server again by opening your Windows Settings, clicking on the time and language tab, opening the date and time menu, and clicking the manual sync button.
Follow these steps to sync your clock manually:
- Open your Windows Settings by clicking the Start button and choosing the gear icon, or by pressing the Windows key and the letter I.

Settings - Click on Time & language in the left sidebar.
- Click on Date & time on the main settings panel.
- Scroll down until you see the section for additional settings. Look for the button labeled Sync now.

When you click this button, Windows immediately reaches out to the internet time server to check the correct time. A small checkmark or a status message appears next to the button once the synchronization finishes. Look at your taskbar clock to verify that the time updated correctly.
What to Do If the Sync Now Button Fails
What to do if the sync now button fails usually involves checking your internet connection to make sure your computer can reach the online time server. If your web browsing works fine but the clock still will not update, the issue is likely a temporary glitch with the internet time server that you can fix by trying a different server or restarting your background services.
When the sync fails, your computer cannot reach the time server over the internet. First, check your internet connection. Open a web page in your browser to make sure you are online. If your internet works fine, the issue might be with the specific time server your computer is trying to contact.
You can change your time server settings using the Windows Control Panel to try a different, more reliable server.
Changing Your Time Server Using the Control Panel
Changing your time server using the Control Panel helps fix stubborn clock issues when the main settings app fails to sync. You can access these advanced server options by opening the classic Control Panel from your start menu search, switching the view to large icons, and selecting the date and time properties window.
- Open the Start menu, type Control Panel, and select the app from the search results.

Control Panel - In the top right corner of the Control Panel window, change the "View by" option to Large icons or Small icons so you can see all the settings clearly.
- Click on the option named Date and Time.
- A small window pops up on your screen. Click on the tab at the top labeled Internet Time.
- Click the button that says Change settings... (Note: This step may require administrator privileges. If a security prompt appears asking if you want to allow this app to make changes, click Yes.)
- In the window that opens, make sure the box next to "Synchronize with an Internet time server" is checked.
- In the drop-down menu labeled "Server," you will see a default server name. Click that menu and choose a different server option, such as the alternative time server provided by your operating system.
- Click the Update now button. You should see a message saying that the clock was successfully synchronized.
- Click OK on all the open windows to save your changes.
Restarting the Windows Time Service (Unique Expert Tip)
Restarting the Windows Time service fixes a frozen background program that prevents your computer clock from updating automatically. You can restart this helper service by opening the system services app from your start menu search, finding the time service in the list, and clicking the restart button to clear out any temporary software glitches.
- Click the Start button, type Services into the search box, and click on the Services app. (Note: This step may require administrator privileges. If a window pops up asking for permission, allow it to continue.)

Settings › Privacy & security › Search - In the long list of services, scroll down until you find the one named Windows Time.

- On the left side of the window, or by right-clicking on the service name, click on Restart. Alternatively, you can click "Stop" and then click "Start."
- Close the Services window and return to your Date & time settings to try clicking the Sync now button again.
Restarting this service forces Windows to wipe its temporary memory regarding timekeeping and start fresh, which clears out stubborn synchronization errors.
Checking Your Time Zone Settings
Checking your time zone settings ensures your computer clock displays the correct local time even when the internet time sync works properly. You can fix an incorrect time zone by opening your Windows Settings, going to the time and language section, and choosing your correct local region from the drop-down menu.
To check and fix your time zone:
- Open your Windows Settings by pressing the Windows key and the letter I.
- Click on Time & language on the left.
- Click on Date & time.
- Look for the option labeled Time zone.
- Check the drop-down menu to make sure it matches your actual local geographic area.
- If you travel often, you can also turn on the switch for Set time zone automatically so Windows figures out your location and adjusts your time zone for you.
Handling Hardware Battery Issues
Handling hardware battery issues is necessary when your computer forgets the correct time and date every time you shut it down or unplug it. Hardware battery failure happens when the small coin-shaped CMOS battery on your computer motherboard runs out of power and needs to be replaced with a fresh one.
Inside every desktop computer and older laptop, a small coin-shaped battery on the main board called the CMOS battery keeps the internal clock running when your computer is unplugged or shut down. If the CMOS battery dies, your computer forgets the time and date every time you power it down. Replacing the CMOS battery inside a desktop computer is usually very simple, though laptop batteries can be harder to reach. If your computer is very old and keeps losing its time upon startup, consider having a local computer repair technician check your motherboard battery.
Summary
Keeping your computer clock accurate is easy when you know how to reset network time synchronization in Windows 11 Date And Time Settings. You can quickly fix a broken clock by using the manual sync button, changing your time server in the Control Panel, restarting the background time service, or checking your time zone settings.
