Answer 1

Finally got the solution:

The point is, NSDate objects don't have a time zone associated with them, and a few releases back someone in Apple decided that NSDate's -description method, which is what NSLog uses, should use GMT+0 and NOT the local time zone for output. (I assume someone had a bug where they corrupted their locale setting, and that caused NSDate's -description method to crash, and so bug reports got filed...)

The short version: Use NSDateFormatter to output dates. Don't use -description.

Answer 2

Are you running iOS version 4.2? If so, there is some kind of issue with the date method, it does not seem to respect your local time zone. For example, if I run your code in the iOS 4.0 simulator, I get this output:

Current Date :: 2011-07-06 10:43:38 -0400

But if I run it in the iOS 4.2 simulator, I get this:

Current Date :: 2011-07-06 14:44:18 +0000

Here is another SO post that describes this in more detail:

NSDate et al woes on iOS 4.2

If you are just looking for the current date and time in an NSString, I use code that looks like this to accomplish that task:

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setFormatterBehavior:NSDateFormatterBehavior10_4];
[formatter setDateStyle:NSDateFormatterShortStyle];
[formatter setTimeStyle:NSDateFormatterShortStyle];
NSString *result = [formatter stringFromDate:[NSDate date]];
[formatter release];
NSLog(@"Current Date v2 :: %@",result);
