Sum a Range of Hours, Minutes, Seconds

[Gregery D Engle]

Assume:

1:03:00
-1:03:00
-0:00:00
8:24:00
9:25:00
-2:54:00

I want to have an Array and return the Total for Hours/Minutes/Second.

Any suggestions?

The only suggestion I have is to do it the old-fashioned way:

Extract all the hoursfrom the hh:mm:ss, multiply by 24 * 60
Extract all the minutes, multiply by 60
Extract and add the seconds.

You now have a total number of seconds.

Divide as needed for desired target time units.

Seems faster than digging thru MSDN and the API reference.

Convert to seconds and store 'em that way. You'll only have a single value to deal
with and you can readily do calculations. Convert 'em back to displayable values
when you need to display 'em.

What storage structure are you using for the hh:mm:ss?

It seems to me that you should be able to do the math directly on the
seconds, minutes and hours (separately) without the need to convert all
to seconds. Just be sure to carry any overflow of seconds or minutes
forward. Of course, this assumes that you are storing the hours,
minutes and seconds in unique vars (array elements).

Bern and Tom,

I think the easiest way to do it would be the way Tom discribes.

I'll post some working code when I'm finished with it.
