TIP
If you wish to set similar scheduling for every day of the week start
by filling in “all” and then changing the desired days.
TIP
Set the stop time earlier than the start time so that the period extends
beyond midnight. Scheduling then stops at the set stop time the day
after.
Scheduling always starts on the date that the start time is set for.
