How to set/force a timezone?

Question

MacOS (14.6.1) believes it's in Japan and stubbornly refuses to change that.

Here's a screenshot:

Problem is, that the Time zone setting is disabled, hence it can't be changed. Question now is, how to force a different timezone?

Any advise is welcome. Thank you.

Can you not change the 'Closest city' at the bottom of the pane? — IconDaemon, Commented Sep 17 at 16:23
@IconDaemon Yes, changing the closest city still works, but only Japanese cities are listed. — SePröbläm, Commented Sep 17 at 18:13
The Github page shows various timezone commands available in Terminal: gist.github.com/ddre54/1e217fbd7e28b5e864dfac31759e66e7 — IconDaemon, Commented Sep 18 at 12:44
@IconDaemon Thank you very much for sharing this link. sudo systemsetup -settimezone Europe/Paris fixed the time zone. GUI is still broken though, but that's not a big thing. — SePröbläm, Commented Sep 19 at 7:13

You should run the systemsetup command to list the available timezones:

sudo systemsetup -listtimezones

The execute this command to set the timezone you need:

sudo systemsetup -settimezone [your timezone]

Examples:

sudo systemsetup -settimezone Europe/Rome

or

sudo systemsetup -settimezone America/Costa_Rica
