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
