Please show the output of
cat /etc/anacrontab
Please also think hard about if you have configured something on your
Debian 11 machines in the past?
I'm not an expert in cron and anacron but in my understanding anacron do
not start cron-jobs after their scheduled time (in hours in minutes).
But I might be wrong.
Maybe you manually configured your Debian 11 in the past that way and
forgot it then?
The upgrade to Debian 12 might overwrite your anacron/cron config with
some default behavior?
It is just an idea and I'll investigate further. It is also possible
that there is a BIT bug.
