Programming, Modifying, or Reviewing an Event that Uses the Astronomical Clock
The astronomical clock uses latitude and longitude coordinates to calculate the dusk and dawn times for each day. To review
the what time the astronomical clock calculated dusk and dawn times will occur for the current day, refer to “Astronomical
Clock Review” on page 5.
In order for the time clock to process astronomical clock events properly, it is necessary to reset the time clock daily. This
