ios - need to get central time in objective-c

I have app where i need to get the current time (CST). I'm trying to use the following code but the NDate is the same as GMT:

NSDate* date = [NSDate date];
    NSLog(@"Time is %@", [date description]);

    [NSTimeZone setDefaultTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"CST"]];
    NSDate* nDate = [NSDate date];
    NSLog(@"Central time is%@", [nDate description])

Beside the fact that the time has not timezone itself, but you have to add a calendar to set it in relation to a time zone as I described here, you should not use a tz abbreviation as described here.
