How to Enable or Disable Set Time Automatically in Windows 11
The “Set time automatically” feature in Windows 11 updates your system clock using internet time servers to keep your computer time accurate within milliseconds. A clock that is even two minutes off can block secure websites, break secure sign-ins, and stop email from working properly.
Windows 11 turns on this setting by default, but you can switch it on or off at any time within the Date & time settings.
Open Windows Settings by pressing Win+I. Navigate to Time & language Date & time. Toggle ‘Set time automatically’ to On or Off to manage automatic time synchronization.
Why use this feature?
The ‘Set time automatically’ feature lets your computer sync its clock with an official Microsoft Time Server. This uses the Windows Time Service (a background program that synchronises your system clock with external time servers), keeping your computer clock matched to official time sources worldwide.
What happens when done?
The “Set time automatically” feature in Windows 11 allows your computer to adjust its own time. This feature will also correct your time zone and daylight saving time (DST). Correctly setting the time prevents issues with expired web certificates and incorrect file creation dates.
How to turn ‘Set time automatically’ on or off
You can change this setting in the Windows Settings app. Press Win+I on your keyboard to open Settings .
Click Time & language on the left, then select Date & time on the right.
Find the 'Set time automatically' toggle. Click it to turn it On or Off.
Troubleshooting Time Synchronization
If your clock is wrong, you can force a sync. In the Date & time menu, scroll down to 'Additional settings'. Click the Sync now button to manually pull the latest time from the internet.
Advanced Registry Configuration
You can configure set time automatically Windows 11 settings through the Registry Editor when the standard settings app does not work. Open Registry Editor with administrator privileges and go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters. Change the Type value to NTP for automatic syncing or NoSync to turn it off, which forces Windows to handle your computer clock directly.
Open the Registry Editor. Navigate to the following path:
The 'Type' registry entry controls automatic time syncing in Windows. Set the 'Type' entry to 'NTP' to enable automatic syncing, or set it to 'NoSync' to disable automatic syncing. You must restart your computer for these registry changes to take effect.
Summary
Your Windows 11 clock usually shows the wrong time when the background service that manages time updates stops running or your network blocks the Network Time Protocol (a networking protocol for clock synchronisation). Keeping your computer clock accurate prevents issues with secure websites and apps, and you can fix most clock drift by restarting the time service or checking your internet connection.
Why is my Windows 11 clock showing the wrong time?
Your clock may be wrong if the Windows Time Service is stopped or if your internet connection is blocking the NTP server. Check your time zone settings first, then try clicking the Sync now button in the Date & time settings menu to force an update from the server.
What should I do if the 'Set time automatically' toggle is greyed out?
You may need to contact your system administrator. Alternatively, ensure you are logged in with an account that has administrative rights to modify system-wide time settings.
Why is Windows automatic time wrong?
If the time on your computer is wrong, the cause is usually one of a few common issues: an incorrect time zone, failed synchronisation, a problem with the Windows Time service, malware, outdated firmware, or a failing CMOS battery.
How to automatically synchronize the date and time in 🪟 Windows 11?
