Title:
Regression after update: timezone changed unexpectedly
Status in tzdata package in Ubuntu:
Incomplete
Bug description:
A user reported this regression on
https://bugs.launchpad.net/ubuntu/+source/tzdata/+bug/2052739:
"""
Hello.
After automatic upgrade of tzdata from 2023c-0ubuntu0.22.04.2 to
2024a-0ubuntu0.22.04
the previously set EST time zone was automatically changed to "America/Adak"
or "America/Indiana/Indianapolis" on all our servers (50+).
Look like a bug in tzdata configure script.
