Time zone used by this site

[Lupp]

When I recently compared, I got:

UTC (by my own UDF):
2025-02-18 13:34:48.171 UTC

forum.openoffic.org:
It is currently Tue, 2025-02-18 15:34

Zone time (Munich, MET, UTC+01:00):
14:34:48 UTC+01:00

Does the site use Eastern European Time?
If so, why?
What did I misunderstand?

I guess it depends on what you set in our User Control Panel. Seems fine for mine:

Thanks.
I don't have any idea for what I may have set a wrong time zone long ago.
But actually the "EET" issue lasted for many years now.

The forum software used to require each member to indicate in the control panel if they were on Daylight Saving Time. So I had to update that setting twice a year. The version we're using now does that automatically as long as the correct time zone and location is provided in User control panel → Board preferences → Global settings → My timezone.

But actually the "EET" issue lasted for many years now.

Surely München uses Central European Time. MET seems to be another name for CET.
