>From what I can tell, and according to my own tests, this is working correctly. I think this is a misunderstanding of a couple things:
1. OnCalendar= can be specified multiple times, allowing multiple trigger times. If you want to completely override the original setting, you need: [Timer] # This empty entry clears the existing list. OnCalendar= OnCalendar=*-*-* 5:00 2. The original timer unit has RandomizedDelaySec=12h, which means the time listed by systemctl list-timers may not reflect exactly what you specify in OnCalendar=.

To reproduce it try to change the timer of apt-daily.timer by calling "systemctl edit apt-daily.timer". Add the following lines: [Timer] OnCalendar=*-*-* 5:00 Save and exit. Reload by calling: systemctl daemon-reload systemctl restart apt-daily.timer Now you can verify that the timer is not changed accordingly by calling: systemctl list-timers --all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/2090941/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
