[gentoo-user] using systemd timers as a cron replacement

[allan gottlieb]

I use systemd and wish to employ timers an analogue of cron.daily.  The system is a laptop that is normally turned off each evening.

As I read the manuals one can have either a monotone or a realtime timer.  But I seem to need features of each.

Specifically, I would like the daily timer to trigger 10 minutes (say) after boot (OnBootSec=600) but not more than once a day (OnCalendar=daily).
The manual and several wiki pages suggest that you can't mix monotone and realtime options.

Am I misreading the manual (and mixing is permitted) or is there a way to achieve my goals with just monotone or just realtime options.

thanks,
allan
