I wouldn't exactly call this a bug... I mean you changed the system time. What did you expect? A pop up telling you that you're crazy for changing the time during an update?
In any case it's a good enough excuse for a break and a beer.
Not really a bug as the above poster said - but that is hilarious
Definitely enough time for you to relive, since apparently its already done it that long ago xD - Either that or thats the worlds oldest Mac xO
