TimeCalc allows you to add together a list of times easily and quickly.
eg.  running lengths of films, or CD tracks

Quick example:
    3:28     ->    3:28 |  0:03:28
    4:11     ->    7:39 |  0:07:39
    3:05     ->   10:44 |  0:10:44
    4:35     ->   15:19 |  0:15:19
    4:31     ->   19:50 |  0:19:50

 1.5         - Third public release
              - Added Offset option
              - Added Clip option (clipboard.device support)
              - Cleaned up memory handling
              - Rewrote string conversion routine.  Can now cope with
                numbers being preceded by text, and can find the end of
                a number properly.
