Where can I get a list of abbreviations for timeZoneWithAbbreviation?

Question

I'd like to do some timezone calculation, using the following API:

NSTimeZone *some_time_zone = [NSTimeZone timeZoneWithAbbreviation:name]; 

however, I am not sure where to find the supported list of abbreviation names. For example, what is the name for the timezone of Siena Italy?

NSLog(@"timezones: %@", [NSTimeZone abbreviationDictionary]);
