NSTimeZone *timezone = [NSTimeZone systemTimeZone];
NSString *timeZoneAbberivation = [timezone abbreviation];
timeZoneAbberivation is printing like GMT+5:30 like that. But I need GMT+5:30 to be printed as IST. (IST is of India/Kolkatta).
Suppose if it is America/Newyork time zone, I need it as EST, etc.
