AM/PM Conventions used: On those activity records where you enter a callback date and time, the program uses this generally accepted convention in performing its indexing and searching: Definition of AM: Midnight Hour [12 hour clock] 12:00 1 2 3 4 5 6 7 8 9 10 11 Hour [24 hour clock] 00:00 1 2 3 4 5 6 7 8 9 10 11 Definition of PM: Noon: Hour [12 hour clock] 12:00 1 2 3 4 5 6 7 8 9 10 11 Hour [24 hour clock] 12:00 13 14 15 16 17 18 18 20 21 22 23 If, for example, you wish to establish a callback time of 15 minutes after midnight, you would enter this time: 12:15 AM Intuitively, one might think to enter "00:15", though this would be incorrect. Another example would be in the instance where you wish to make an appointment at 30 minutes after a noon lunch. You would then enter: 12:30 PM
