Time zone database regression going from 1.88 to 1.89
When upgrading from 1.88 to 1.89 we've encountered an issue with the system time zone DB. In our tests we initialize a jiff::tz::TimeZone with CET and get the following error:
failed to find timezone 'CET' in time zone database
I suspect that the problem lies in /usr/share/zoneinfo, at least that's what jiff documentation would suggest.
Lastly, we've been using the latest tag and when I downgraded to 1.88 it works as expected.
The root cause seems to stem from the fact that trixie moved timezones that don't follow the current tzdata naming convention into tzdata-legacy. You are seeing this change happen on the switch to 1.89.0 because latest tag switched to trixie not long after 1.89.0 was released.
As for solutions, installing tzdata-legacy in the test container would fix the issue, but it would probably be better to switch to a supported timezone.
