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 difference between these two integers using a 60 seconds and minutes scale?

So if

time 1 = 161500 time 2 = 171500  timedifference = 003000 

Answer 1

NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; [dateFormatter setDateFormat:@'HHmmss'];  NSDate *date1 = [dateFormatter dateFromString:@'161500']; NSDate *date2 = [dateFormatter dateFromString:@'171500'];  NSTimeInterval diff = [date2 timeIntervalSinceDate:date1]; // diff = 3600.0
