Hi, I just realized that kmail2 6.3.2 uses a long format for inserting the time including the name of the time zone when replying to an e-mail. Just have a look at some of the recent answers in this mailing list, e.g. the one from Martin 2 days ago:
> MERLIN Philippe - 10.03.25, 10:51:05 Mitteleuropäische Normalzeit: Another e-mail from Martin from 2025-02-12 shows > Erwan David - 12.02.25, 10:17:00 MEZ: And of course I see this in my own e-mails as well. To me it's a little bit annoying that the time zone is spelled out. I use a workaround and changed the corresponding templates to use '%OTIME' instead of '%OTIMELONG' but maybe there is a better fix.
