I copied some text from NSDate Reference as below, please check Return Value,
it is said the format will be in YYYY-MM-DD HH:MM:SS ±HHMM, but I got as below
in my app, so the reference is mistake? or code in mistake?

<b>descriptionWithLocale:</b>
Returns a string representation of the receiver using the given locale.
- (NSString *)descriptionWithLocale:(id)locale
Parameters
locale
An NSLocale object.
If you pass nil, NSDate formats the date in the same way as the description
method.
On Mac OS X v10.4 and earlier, this parameter was an NSDictionary object.
If you pass in an NSDictionary object on Mac OS X v10.5, NSDate uses the
default user locale—the same as if you passed in [NSLocale currentLocale].
Return Value
A string representation of the receiver, using the given locale, or if the
locale argument is nil, in the international format <i><b>YYYY-MM-DD HH:MM:SS ±HHMM</b></i>,
where ±HHMM represents the time zone offset in hours and minutes from GMT (for
example, “2001-03-24 10:45:32 +0600”)
