GetFirstPartOfOccurrencesWithNoEndDates leads to ArgumentOutOfRangeException when adding 'no end date' recurring appt at DayStartTime in DayView

[Martha]

When I try to add a recurring appt with no end date that starts at the same time my day view schedule starts, I get the following exception when saving the appt:
