This is in connection with the IFLZonePlusOne whenIsSunsetToday() function -- at first the alarm will just consist of sending an email. Also, there may be a positive or negative offset in terms of optimum pretty sunset time vs actual sunset time, and or whether say a five-minute advance-notice period would be wanted.
