Hello Michael, thanks for your prompt reply.

OK, I acknowledge that the network-online.target check is not reliable
enough, I was aware of that.

But anyway, let's pretend the network check is completely absent.

Why is the service triggered *immediately* during wake-up?
It should wait at least 5 min (OnActiveSec=5min) or be triggered on the
basis of the calendar scheduling (OnCalendar=*-*-* *:20) with a random
delay (RandomizedDelaySec=20min).

And it should *not* catch up with missed execution chances (since the
timer is *not* a Persistent=true one).

What am I missing here?
