ios - Wrong date and time in NSDateDormatter -

i want create nsdate 2 nsstrings represent time , date.

look @ code:

nsdateformatter *form = [[nsdateformatter alloc] init];  [form setdateformat:@"hh:mm dd.mm.yyyy"];  nsdate *notdate = [form datefromstring:[@"" stringbyappendingformat:@"%@ %@",z.time,z.date]];  nslog(@"%@ // %@",[@"" stringbyappendingformat:@"%@ %@",z.time,z.date],notdate); 

log show me numbers:

12:00 12.05.2013 // 2013-05-11 18:00:00 +0000 

on left side - 2 strings, on right - date

first got 12:00, when second 18:00! besides, got different days!

why different?

if change

[form setdateformat:@"hh:mm dd.mm.yyyy"]; 

to

[form setdateformat:@"hh:mm dd.mm.yyyy"]; 

it use 24 hour format.

nslog(@"%@ // %@",[@"" stringbyappendingformat:@"%@ %@",z.time,z.date],notdate); 

should output 00:00 12.05.2013 // 2013-05-11 18:00:00 +0000 , explains everything:

the nsdateformatter takes current locale in account if dont manually change it, while internally every nsdate object saved in gmt (hence +0000).
according profile located in perm — 6 hours ahead of gmt.

so dates same, once printed timezone in account, once without.
