OK, now this is a bit offtopic since it concerns not prey but fcron.
I am going to ask anyway since it is important in an indirect way though...

So, how can I make cron (fcron in this case) keep real time on Jolla?
I have installed fcron-3.0.6-3 but I noted that it behaves in not so nice way; if my Jolla is sleeping (like, display off) and a crontab event should trigger it just doesn't wake up. The event is missed completely, not even deferred to when the device wakes up I believe.
