Covert string with timezone to Date

Here is the date string

NSString * dateString = @"Mon Sep 29 14:40:00 2014 PET";

How to convert it into NSDate?

NSDateFormatter * dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setLocale:[NSLocale localeWithLocaleIdentifier:@"en_US_POSIX"]];
[dateFormatter setCalendar:[NSCalendar currentCalendar]];
[dateFormatter setDateFormat:@"EEE MMM dd HH:mm:ss yyyy zzz"];
NSDate* date = [dateFormatter dateFromString:dateString];

Above code doesn't work. what is the correct date format for above case?

the problem is your timezone definition (PET), because that is not on list of the recognisable timezones (please don't ask why not); this timezone is mostly known as UTC-5 in Apple's system, therefore:

NSString *_dateString = @"Mon Sep 29 14:40:00 2014 PET";
_dateString = [_dateString stringByReplacingOccurrencesOfString:@"PET" withString:@"UTC-5"];
NSDateFormatter *_dateFormatter = [[NSDateFormatter alloc] init];
[_dateFormatter setLocale:[NSLocale localeWithLocaleIdentifier:@"en_US_POSIX"]];
[_dateFormatter setCalendar:[NSCalendar currentCalendar]];
[_dateFormatter setDateFormat:@"EEE MMM dd HH:mm:ss yyyy zzz"];
NSDate *_date = [_dateFormatter dateFromString:_dateString];
NSLog(@"date : %@", _date);

and the console says:

date : 2014-09-29 19:40:00 +0000

which is the correct representation of the original date in GMT+0 timezone.
