Time Calculation

im sorry to ask this im sure its a very simple calculation but its really frustrating me :mad:

if i take 2 int variables the 1st is a time such as 1345 (1:45pm)
the 2nd a duration of time such as 530 (5hours 30min)
how do i add them together and get the correct time of 1915 (6:15pm)?

> if i take 2 int variables the 1st is a time such as 1345 (1:45pm)
Convert to minutes - as 13*60+45

Then do the reverse to recover hours and minutes when you're done.
