+Over systemd timers:
+- mnemonic syntax
+- less complexity for jobs, no need for a `<job>.timer` file distinct
+  from the `<job>.service` file,
+- can use a file timestamp to ensure minimum waiting time between two
+  runs, even across reboots
+- very robust with respect to external time changes
+- randomized delays
+- variable slack
+- ad-hoc usage possible, just run the program from command line

+* if we notice time moved backwards, recompute the time until the event
 * if the event is in the future, recompute the time it takes, possibly
