If you want to be able to have the zero padding as optional as well as leap seconds:

/^((0?[1-9])|(1[0-2])):[0-5]\d:(([0-5]\d)|(60)) [AP]M$/

The breakdown:
(0?[1-9]|1[0-2]) 1-9 (with optional leading zero) or 10-12
[0-5][0-9] 00-59 (0-5 for first digit, 0-9 for second)
([0-5][0-9])|(60) Leap seconds
[AP]M AM/PM
