For PDT, I would want "-0700". I'm getting a date in the past to determine how long ago something happened. NSDate *then = [NSDate dateWithString:@"1976-04-01 12:34:56 -0700"]; // Note the hard-coded time zone at the end I'll be constructing the date string elsewhere but I don't know how to access the local time zone. I read the App...

I go to location B I know the latitude and longitude and the current time. How to calculate the time difference between the two current points .. (in UTC) ...
From what I understand, calling NSLog(@"Local Time Zone %@",[[NSTimeZone localTimeZone] name]); gives you the local time zone of the device. What it's giving me is "US/Central", and I can't find that anywhere in the list of abbreviations in [NSTimeZone abbreviationDictionary], or the list of time zone names in [NSTimeZone knownT...
I'd like to (at least) get the name of the country for a time zone. This is not provided by any of the potential methods: name, localizedName:locale:, description I notice that the built in iPhone clock App has access to this information, as it describes London as "London, England". Thanks. ...

Hi, I have a date, 2010-08-23 13:30:00 -0400 and I'm trying to get it in the UTC +2 time zone. The difference in seconds is 21600 but when I call [[NSDate alloc] initWithTimeInterval:interval sinceDate:sourceDate];, I get 2010-08-24 01:30:00 +0200 which should be 2010-08-23 19:30:00 +0200. Any idea what I'm doing wrong? ...
Is there a way to lookup a timezone abbreviation when only the temporal offset is known? Example: Say i'm given the offset of GMT -5, i'd like to display the abbreviation of EST (assuming US) as apposed to GMT -5. If you initialize a NSTimeZone object with [NSTimeZone timeZoneWithName:@"America/Argentina/Buenos_Aires"], you can get th...
