AÂ time zoneÂ is a geographical region in which the same time is used. Typically, but not always, adjacent time zones are one hour apart. The time in any of the world’s time zones can be expressed as an offset from Coordinated Universal Time (UTC).
You can choose to let Windows 11 set your time zone automatically based on your region, or you can set the time zone manually.
This tutorial will show you different ways on how to manually change the time zone for all users in Windows 11.
