My computer not updating time
This means that most users never have to worry about setting the date and time in Windows, or correcting the time after events like power outages or a switch to daylight-saving time.
But sometimes a user’s Windows clock can go awry and display the incorrect date or time, usually due to hardware issues, a temporary loss of Internet connectivity, or online synchronization problems.
You may also see clocks for additional time zones here if you have previously enabled that feature.
From the Win X Menu, open Settings service and double-click on it. Turning it off is for a few legacy edge cases and a couple of places in the world that don't currently have an appropriate entry in the list of time zones.
