You might have an issue with incorrect time setting in Windows 11 after installing Ubuntu alongside Windows 11. After installation, You’ll find different time displays in Windows 11.
One of the reasons for this is the different time methods of Windows 11 and Ubuntu Linux. By default, Windows uses local time, but Ubuntu uses UTC. So, the trick is to use the same time standard in both systems to correct the time settings.

We can solve this issue by setting UTC / GMT time standard in Windows 11 via the following steps.
