Bug description

28.0.4.1 (community docker, Apache), Windows/Firefox. User interface is set to en-UK and shows correct "base" interface language. but dynamic string when the job effectively run localizes in German (which might be my region)

Transifex translation is "Last job ran {relativeTime}."

The problem is related to "Locale: German" switching to English makes the string to "full English".

addition

testing the issue I found many locale definitions are wrong e.g.

using AM/PM format and MM/dd/yyyy format is not common in Germany and Switzerland. both use "dd.MM.yyyy HH.mm" format without AM/PM

Steps to reproduce

1. set you personal settings at https://nextcloud.mydomain.tld/settings/user to Language "English (US)" and Locale: "German"
2. visit "Basic Admin settings" at https://nextcloud.mydomain.tld/settings/admin
3. observe the main language is English while "{relative time}" is localized in German

Expected behavior

• localized relative time must follow the main language
• locales must follow common country standard
