Bug Description
[ Impact ]
The 2024b release contains the following changes:
* Improve historical data for Mexico, Mongolia, and Portugal.
* System V names are now obsolescent.
* The main data form now uses %z.
[ Test Plan ]
Test cases were added to the autopkgtest to cover the testing:
* python: test_2024b
* python-icu: test_2024b (only for focal and newer)
So the test plan is to check that the autopkgtest succeeds.
[ Other Info ]
The autopkgtest for chrony is flaky on jammy and newer (see bug #2002910).
There are backward-
Names present only for compatibility with UNIX System V
(last released in the 1990s) have been moved to 'backward'.
These names, which for post-1970 timestamps mostly just duplicate
data of geographical names, were confusing downstream uses.
Names moved to 'backward' are now Links to geographical names if
there is an exact match since 1970, and remain Zones otherwise.
Those needing the previous TZDB behavior, which does not match any
real-world clocks, can find the old entries in 'backzone'.
(Problem reported by Justin Grant.)
We need to exclude this change for the SRU since it can/will break user setup (e. g. the user from bug #2055718) and it will break a handful of tests (including dateparser, pandas, posrtesql-16). See https:/

Importing Debian's tzdata 2024b-1 is probably not a good way to do this, as it also changes to a newer format that saves space but breaks python3-dateutil and hence several other packages:

This is probably fixed in 2024b-2.
