Question

I have got two timevalues in the format: %H%M%S (E.G.161500)

These values are text-based integers.

Is there a simple function in Cocoa that calculates the diffe

Answer 1

The class for manipulating dates is NSDate. The method for getting time intervals is -timeIntervalSinceDate:. The result is a NSTimeInterval value, which is a double representing the interval in seconds.

You can create a NSDate object from a NSString with +dateWithString:, provided that your date is formatted as 2001-03-24 10:45:32 +0600.
