In case of bug report: Expected behaviour you didn't see
The timer should run once every hour, but it runs only once.
In case of bug report: Unexpected behaviour you saw
The timer shows the scheduled next time as in the past.
In case of bug report: Steps to reproduce the problem
- Create a target for the timer.
$ cat > ~/.config/systemd/user/timer-hourly.target <<EOF
[Unit]
Description=Hourly Timer Target
EOF
- Create a timer.
$ cat > ~/.config/systemd/user/timer-hourly.timer <<EOF
[Unit]
Description=Hourly Timer
[Timer]
OnCalendar=hourly
Persistent=true
Unit=timer-hourly.target
[Install]
WantedBy=timers.target
EOF
- Enable and start the timer.
$ systemctl --user daemon-reload
$ systemctl --user enable timer-hourly.timer
$ systemctl --user start timer-hourly.timer
- The timer will now run once.
Subsequent times will be in the past and the timer will not run again.
If the computer reboots or you restart the timer, it correctly notices, that it missed the last execution and executes once, but after that it again calculates the wrong time.
