Hi. Me again. :) AFAIK the Time Format selector (in Settings -> Details -> Date & Time) sets a dconf value which affects the clock in the top bar only. I just tested on 19.04, and can't find that it affects gnome-terminal at all.
It's possible that bug #1842256 affects you. To find out, can you please run these two commands: cat /etc/default/locale cat ~/.pam_environment and show us the output here. ** Changed in: gnome-control-center (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1843426 Title: Time format setting no longer applies to terminal shell To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1843426/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
