The game history dates seem out of wack. If I play a game with a friend and go to game history I can see the game with the correct date. If I do the same but search for the gamer tag of the friend his game history shows 24 hours more recent ? Am I missing something?
You can see this easily if you play with a friend. Look up your game history search his name out and look at his. This has to be some kind of bug.
