After extensive stress testing of my authenticator with collaborative effort from online-stopwatch, it would seem that key chain authenticator codes die out somewhere around the 11 minute mark. Given the right instruments and care factor I could obtain more accurate results, but in my findings an authenticator code was still able to be used at about 11 minutes and was no longer valid at approximately 12 minutes [separate codes used each pass obviously].
