NSDateFormatter Adding 11 Extra Minutes when formatting

Question

I seem to be adding +11 minutes to my desired date values when I am converting them using NSDateFormatter.

The startDate and endDate as NSDates on MyObject, printed to the console:

START DATE: 2011-11-28 18:00:00 +0000

END DATE: 2011-11-28 20:00:00 +0000

My NSDateFormatter:

NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease];

[formatter setDateFormat:@"hh:MM a"];
[formatter setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];

Setting the dateRangeString:

NSString *dateRangeString = [NSString stringWithFormat:@"%@ - %@", 
                                 [formatter stringFromDate:self.startDate],
                                 [formatter stringFromDate:self.endDate]];

The wrong resulting dateRangeString:

Date Range: 18:11 PM - 20:11 PM

Why is it adding an extra 11 minutes to the times? What am I doing incorrect in my conversion? Am I forgetting something silly? SO, please help my sanity!

[formatter setDateFormat:@"HH:mm a"];

MM is for months.

Formatting NSDate into particular styles for both year, month, day, and hour, minute, seconds

Noob move, I'm tempted to just delete this. use `mm` – kturner Nov 29 '11 at 01:28
Easy mistake to make, which is why it was one of the first things I checked. – Hot Licks Nov 29 '11 at 01:51
