- due to supervision, have custom logs
- due to no centralized daemon, no fuzzing with multiple users/permissions
- very robust with respect to external time changes
- can use a file timestamp to ensure minimum waiting time between two runs, even across reboots
- randomized delays (some cron have that)
- variable slack (no need for anacron)
- ad-hoc usage possible, just run the program from command line
