Some of the non canononical timezones are not present in Ubuntu Noble,
it would be a better practice to only use canonical timezones in data
and tests.
Note that this is not a real fix for all cases since the database that
ran on Ubuntu Jammy and are moved to an ubuntu Noble server will have
the issue with timezones already in database.
One of the possible fix would be to manage that during upgrades, but
this isn't a verry flexible solution since upgrade are meant to manage
chyange of version, not change of server. If an old 17.0 versions needs
to be moved to a Noble server, this won't work.
Another solution would be to install package like tzdata-legacy that may
keep the old timezones but it is not the only think since TAI-10 are
also in this package. This solution is not ideal because non canonical
timezone will still be shown in the dropdown. We would need to filter
them.
A last solution would be to add the support for those old timezones by
monkeypatching the lib. This way, only new timezones would be shown but
non canonical one won't crash when used. This is not ideal either
because we may need to keep this for a while. But in combination with
the upgrade solution, it may work proprely.
