Bug#1124111: trixie-pu: package tzsetup/1:0.132+deb13u1

Control: affects -1 + src:tzsetup

Hi,

[ Reason ]
We've received installation reports from users telling us their
locations weren't being taken into account timezone-wise. That's the
case at least for Argentina (multiple reports), and for Ukraine. Both
are fixed in unstable already.

As far as I understand[1] that's due to legacy names being split out
from the regular tzdata package.

  1. https://lists.debian.org/debian-boot/2025/12/msg00190.html

Whatever the exact reasons, the fact is bookworm was accepting both
pairs of names (Etc/UTC added for reference):

    $ for tz in America/Argentina/Buenos_Aires America/Buenos_Aires Europe/Kyiv Europe/Kiev Etc/UTC; do TZ=$tz date; done
    Sat 27 Dec 21:23:26 -03 2025
    Sat 27 Dec 21:23:26 -03 2025
    Sun 28 Dec 02:23:26 EET 2025
    Sun 28 Dec 02:23:26 EET 2025
    Sun 28 Dec 00:23:26 UTC 2025

while trixie doesn't anymore:

    Sat 27 Dec 21:23:16 -03 2025
    Sun 28 Dec 00:23:16 America 2025
    Sun 28 Dec 02:23:16 EET 2025
    Sun 28 Dec 00:23:16 Europe 2025
    Sun 28 Dec 00:23:16 UTC 2025

Note how the second of each pair (legacy name) gets the area reported,
alongside with the same data as UTC…

[ Impact ]
Affected users get UTC instead of a location-appropriate timezone.

[ Tests ]
Test-installations in Spanish (location = Argentina) and Ukrainian
(location = Ukraine) with a custom ISO using the proposed package
confirmed the correct timezone is set and giving appropriate time
information in the installed system.

[ Risks ]
I'd hate to jinx it so I'll just stay very low risks: the source package
gets two substitutions (the two affected locations), which after a build
under cowbuilder are confirmed to be the only two changes according to
diffoscope.

[ Checklist ]
  [x] *all* changes are documented in the d/changelog
  [x] I reviewed all changes and I approve them
  [x] attach debdiff against the package in (old)stable
  [x] the issue is verified as fixed in unstable


Thanks for your time!


Cheers,
