If the times are stored as normal Excel times, they just numbers
(representing a fraction of a 24 hour day, 0.25 = 6:00, 0.5 =
12:00, 0.75 = 18:00, etc), so you can simply add them as you
would with regular numbers, using '+' or SUM. Format the result
cell with a custom number format of [hh]:mm or [hh]:mm:ss .

How can I add two or more sets of hours:minutes:seconds? For
example, if I
add 12hr30min00sec to 1hr45min45sec I should get
14hr15min45sec.
