I am not sure now if it was something wrong with the bot tzdata, I reinstalled the tzdata packages
and reconfigured the timezone and now 'TZ=UTC date -d '@0' +%H:%M' does show the expected
00:00.

Indeed, although the workaround shouldn't change the expected result, the issue I am observing
on some machine does not make sense (TZ=UTC date -d '@0' +%H:%M' not showing 00:00).

I will hold this and investigate further.
