how to change clock

Open Date & time from Windows Settings instead of the unresponsive taskbar clock, then correct both the time and time zone.

Correct the clock

1. Press Windows key + I to open Settings.
2. Select Time & language → Date & time.
3. Turn Set time automatically On.
4. Turn Set time zone automatically On, or turn it Off and choose the correct entry under Time zone.
5. If the time is still wrong:
   • Turn Set time automatically Off.
   • Next to Set the date and time, select Change.
   • Enter the correct date and time, then select Change.

These are the supported Windows 11 controls for the taskbar clock’s time and time zone.^1^

If the clock still will not open

Normally, selecting the taskbar clock opens the calendar and notification center.^2^ After correcting the time:

1. Select Start → Power → Restart.
2. After Windows restarts, select the clock again.
3. If the clock has disappeared, press Windows key + I, then go to Time & language → Date & time and turn Show time and date in the System tray On.^1^

If the setting changes but the displayed time becomes wrong again after every shutdown, further details are needed—particularly whether the entire system tray is unresponsive or only the clock, and whether the computer is managed by an employer or school.
