I\'m initializing my NSDateFormatter thusly:
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setLocale:[[[NSLocale
Remove the trailing 'z' character from the format string if you don't want to display the time zone.
EDIT
On the other hand, if you just want to display the timezone name, just make the 'z' uppercase. ((edit: leave the 'z' lowercase for named timezone, i.e. PST and uppercase 'Z' for -0800))
EDIT
Lowercase 'z' works fine for all the other timezones, but unfortunately GMT is a special case. So the easiest thing to do is to just omit the 'z' and append " GMT" to the formatted date.
