In the sentence from me above I've wrtten taht I don't use Windows.
I haven't written that I would get issues when using UTC, but I also
don't get issues, when I'm using local time.
Nobody did explain how the BIOS should save files with German time, if
the clock is set to UTC.
Again, some people have a BIOS and do use it ;). Some people save BIOS
settings to e.g. USB. No Linux, no Windows, it's just the BIOS.
If the clock does use local time, then the time for all BIOS and all
Linux files are ok.
If the clock is set to local time, then the time for the BIOS files is
wrong, only the files for Linux are ok.
So, what is better?
All files have the wanted, correct time or just Linux files have the
correct time?
Don't mention Windows again and again.
Do you have a BIOS or have you some magic Linux replacement for the
BIOS?
