The "CET" time zone has vanished between Debian 12 and 13.

For good reasons. This is not a time zone but a time zone abbreviation. We should use "Europe/Paris" instead.

Now we have a crisis meeting because it's a major breaking change that can't be fixed because nobody knows how to set the time zone to a different value in the application 🤦‍♂️

It's not even a timezone abbreviation, it's a name for the offset of 1 hour to UTC. In summer, many countries stay in their timezone while the offset changes from CET to CEST (UTC+2).

Don't confuse timezones with UTC offsets.
