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?

descriptionWithLocale:
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 NSDictionaryobject on Mac OS X v10.5, NSDate uses the default user localethe 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 YYYY-MM-DD HH:MM:SS ±HHMM, where ±HHMM represents the time zone offset in hours and minutes from GMT (for example, 2001-03-24 10:45:32 +0600)
