This tutorial will show you how to turn on or off set time zone automatically for all users in Windows 11.
A time zone 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.
Starting with Windows 11 build 23486, if location settings are disabled, a warning is now shown to the user, urging them to enable location settings to ensure accurate time zone adjustments. This warning provides helpful information to the user, helping them understand why their time zone may not be correct and guiding them towards resolving the issue.
