Dear Sven, Bob, Philip,
thank a lot for your hints! The daylight saving time (DST) is indeed the
problem, so I have to use the '-u' option of date for proper working of my
script.
Sorry for bothering, I should have thought myself about this. Maybe an
additional hint in the error message to the DST problem would help other
users (like (DST gap))?
thanks again
Klaus

I used the command

Date has a format like this
"2003-03-30 02:08:17"
However, 7 of 42048 randomly distributed dates in the list failed:
date: ungültiges Datum „2003-03-30 02:08:17“
date: ungültiges Datum „2003-03-30 02:25:58“

date: ungültiges Datum „2007-03-25 02:03:47“
For me, this seems to be a bug in the date reading part. The critical
combination seems to be end of March and '02' as hour.
Yes, it's the non-existent hour during DST adjustment on the last Sunday
in March. These dates are indeed invalid in the German timezone.
