iphone - Convert GMT time to local time -


i got current gmt time - 2013-05-15 08:55 am

my current local time - 2013-05-15 02:06 pm , time zone - asia/kolkata

i tried convert above gmt local time code

   nstimezone* sourcetimezone = [nstimezone timezonewithabbreviation:@"asia/kolkata"];    [dateformatter settimezone:sourcetimezone];         // timestamp - above gmt time     nsdate *datefromstring = [dateformatter datefromstring:timestamp];     nslog(@"local time %@",datefromstring);

but give me wron time - 2013-05-14 19:04:00 +0000 instead of 2013-05-14 02:06 pm

why happens? please me clear this.thanks in advance

nothing going wrong, nsdate instance never have timezone ( gmt, indicated +0000 timezone in date description).

what telling dateformatter in code timezone of date want parse asia/kolkata want gmt.

first need make nsdate object input date string time zone set correct time zone, gmt indicated. 

nstimezone *gmttimezone = [nstimezone timezonewithabbreviation:@"gmt"]; [dateformatter settimezone:sourcetimezone]; nsdate *datefromstring = [dateformatter datefromstring:timestamp]; nslog(@"input date gmt: %@",datefromstring);

then when present date string use :

nstimezone* sourcetimezone = [nstimezone timezonewithname:@"asia/kolkata"]; [dateformatter settimezone:sourcetimezone]; nsstring *daterepresentation = [dateformatter stringfromdate:datefromstring]; nslog(@"date formated local time zone: %@",daterepresentation);
