Greetings! I must be seeing things. Look at this excerpt from the iPhone OS reference library:

addTimeInterval: Returns a new NSDate object that is set to a given number of seconds relative to the receiver. (Deprecated. This method has been replaced by dateByAddingTimeInterval:.)

However, it is nowhere to be found in the docs, nor in the headers. If I look at the Mac OS SDK, then I find it.

Typo? Just keep using addTimeInterval: after all??

Looks like a typo to me as I see the same thing on my system as you do. Perhaps they intended to deprecate the method as described but cut it at the last minute, with the incorrect text still in place.

It's actually an error in the docs. addTimeInterval: is deprecated in Mac OS X 10.6 but not in iPhone OS 3.1.2.

You can look at the NSDate.h in MacOS and in iPhoneOS and you'll see the difference.

NSDate.h in iPhone OS

- (id)addTimeInterval:(NSTimeInterval)seconds;

and NSDate.h in Mac OS 10.6

- (id)addTimeInterval:(NSTimeInterval)seconds DEPRECATED_IN_MAC_OS_X_VERSION_10_6_AND_LATER;
- (id)dateByAddingTimeInterval:(NSTimeInterval)ti AVAILABLE_MAC_OS_X_VERSION_10_5_AND_LATER;
