If you don't want to just divide it out, try this. It may be close enough for your purposes. Note: It doesn't account for sub-second precision. (setSecond takes an NSInteger).

NSDateComponents* c = [[[NSDateComponents alloc] init] autorelease];
[c setSecond:32025.89];

NSCalendar* cal = [[[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]
                   autorelease];

NSDate* d = [cal dateFromComponents:c];

NSDateComponents* result = [cal components:NSHourCalendarUnit |
                                           NSMinuteCalendarUnit |
                                           NSSecondCalendarUnit
                                  fromDate:d];

NSLog(@"%d hours, %d minutes, %d seconds",
    [result hour], [result minute], [result second]);
