To clarify: You want to be able to say something like:

00:10:00.00 * 20 = 03:20:00.00     (10 minutes * 20  is 3 hours 20 minutes)

00:45:00.00 + 00:20:00.00 = 01:05:00.00   (45 minutes + 20 minutes is 1
hour and 5 minutes)

eg: Take a formatted time, and apply those math functions to it.  Is
that about right?
