When I run this code below the PST and AKST timezones are never run... Both of these are run perfectly:

NSTimeZone *pacificTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"PST"];
NSTimeZone *alaskaTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"AKST"];

But neither one of these are run:

}else if ([local isEqual: pacificTimeZone]) {
    NSLog(@"Pacific");

} else if ([local isEqual: alaskaTimeZone]) {
    NSLog(@"Alaska");

Any suggestions?

    NSTimeZone *local = [NSTimeZone localTimeZone];
    NSTimeZone *centralTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"CST"];
    NSTimeZone *easternTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"EST"];
    NSTimeZone *mountainTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"MST"];
    NSTimeZone *pacificTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"PST"];
    NSTimeZone *alaskaTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"AKST"];
    NSTimeZone *honoluluTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"HST"];

    NSLog(@"LOCAL TIME ZONE: %@", local);

    NSLog(@"CST TIME %@", centralTimeZone);
    NSLog(@"EST TIME %@", easternTimeZone);
    NSLog(@"MST TIME %@", mountainTimeZone);
    NSLog(@"PST TIME %@", pacificTimeZone);
    NSLog(@"AKST TIME %@", alaskaTimeZone);
    NSLog(@"HST TIME %@", honoluluTimeZone);


    if ([local isEqual: centralTimeZone])
    {
        NSLog(@"Central");

    } else if ([local isEqual: easternTimeZone]) {
        NSLog(@"Eastern");

    } else if ([local isEqual: mountainTimeZone]) {
        NSLog(@"Mountain");

    }else if ([local isEqual: pacificTimeZone]) {
        NSLog(@"Pacific");

    } else if ([local isEqual: alaskaTimeZone]) {
        NSLog(@"Alaska");

    } else if ([local isEqual: honoluluTimeZone]) {
        NSLog(@"Honolulu");

    }

Thanks!
