where'd the original question go ?? It was something like "how do i add the times 12:45 10:00 01:45?" (didn't specifiy if the answer should be 24:30 or 1:00:30)

Anyways, besides the other reply, the Add_Delta_YMDHMS() function in Date::Calc might be of interest..

Update: The OP was almost exactly the same as time calculation, which has some good replies already ..
