similar to PVE, copying over the remaining commit message:
Using 00:00 with relying on the implied default is sub optimal as its
a bit of a magic example that new users may not understand as easily.
So spell it out explicitly, even if there'd be a shorter version
possible.
We also had some request for the once-daily every day, and its a
sensible example to have in general, could help getting the
difference between an hour list and a single one.
