I want to show time difference on a NSTextField which I have obtained with

	NSDate* startTime = [self valueForKey:@"startTime"];
	NSDate* endTime = [self valueForKey:@"endTime"];
	NSTimeInterval interval = [endTime timeIntervalSinceDate:startTime];
	return [NSDate dateWithTimeIntervalSinceReferenceDate:interval];

Seems ok.


The format must be <days>:<hours>:<minutes> . The format string %d:% I:%M show for identical startTime and EndTime (interval is 0 in other words) 1:1:0. Day and hours has always one more as expected. Day will also not be greater then 31 because it is the day of month.

You can format a date with NSDateFormatter. Here is an example code that does that (using another format, but you can handle that):


NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease];
[formatter setFormatterBehavior:NSDateFormatterBehavior10_4];
[formatter setDateFormat:@"EEE, MMM d, hh mm a"];
return [formatter stringFromDate:[NSDate date]];


The format string uses ICU format, not standard unix date formating format.
