[Amr Ibrahim]

Package: gnome-control-center
Version: 1:49.1-1
Severity: important

Hello,

Upstream issue:
https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues/3599

In 'System' > 'Date and Time':

The 'Busingen, Germany' time zone displays the incorrect time. It shows UTC,
but it should show UTC+1 (CET).

The timedatectl command shows the correct time.

$ timedatectl status
               Local time: Sa 2025-11-01 20:19:45 CET
           Universal time: Sa 2025-11-01 19:19:45 UTC
                 RTC time: Sa 2025-11-01 19:19:45
                Time zone: Europe/Busingen (CET, +0100)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

Best,
Amr
