iOS Different display by NSDate and NSDateFormatter

[namanhams]

Here is my code :

NSString *s = @"Wednesday, 19 January 2011";
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:@"EEEE, dd LLLL yyyy"];
NSDate *date = [df dateFromString:s];
NSLog(@"%@",date);  
NSLog(@"%@",[df stringFromDate:date]);

Here's the output :

2011-01-18 16:00:00 +0000
Wednesday, 19 January 2011


So the 2nd output line is as expected, while the 1st output line is totally strange.
How come it's like that ?

NSDate has no locale or time zone associated with it. When you log it like that it logs as if it were in GMT. This was a change, I think in 4.0. Before that it would print the date using your own locale and time zone. You should never use something like printing a date using %@ to show a date to a user. Use the date formatter, and it will give you what you want (once you figure it out).

Many thanks for that !
