I have two times formatted as strings without associated dates and I want to determine the interval between them. I found lots of info on NSDate and NSCalendarDate and a few references within those to NSTimeInterval, but I haven't been able to find anything on NSTimeInterval directly.

For instance, I have the following times in a text file and I want to get the interval between them (in seconds is fine):

20:15:30
20:25:30

I've scanned them into two variables using NSScanner, but I don't know where to go from there.

thanks,
kman

NSTimeInterval is just defined as a double.
But personally, I'd probably just scan the numbers into ints and do the math myself. It's easy, and it's faster than screwing around with NSDates.
