'12am' places the item at noon in the agenda. It is arguable whether 00:00 should be used instead of 24:00. Personally, I prefer it the way it is, where midnight events are placed at 24:00 because if I have something scheduled/due at midnight, I'd like to see it on the agenda for the day *preceding* the event/item. However, the issue I differ on is the interpretation of 12am as noon and 12pm as midnight. Although they are both ambiguous, it seems that 12am is more typically associated with midnight, while 12pm is associated with noon. One explanation goes like this: Since the 24-hour clock runs from 00:00:00--23:59:59, then 00:00:00-11:59:59 is AM and 12:00:00-23:59:59 is PM. Just curious....is the current mapping a deliberate choice or a bug? Dan
