NSDateFormatter dateFromString coming back null

I am trying to get a string date into a date object so I can do some comparisons. My code is as follows:

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"yyyy/MM/dd_hh:mm:ss"];
NSDate *date = [formatter dateFromString:@"2012/02/06_20:35:59"]; 
[formatter release];

NSLog(@"date = %@", date);

My NSLog is showing that *date = null;

Any help is appreciated. Thanks.

    [formatter release];

    NSLog(@"date = %@", date);

Does't your format need to be yyyy/MM/dd_HH:mm:ss?

hh is 0-12 where as HH is 0-23.

For reference, here is the doc where I got that nugget of information from - http://unicode.org/reports/tr35/tr35-10.html#Date_Format_Patterns
