When Joey resets the alarm clock in the bedroom, it reads around 10:08, even though it's supposed to be a little after 6:30. After he adjusts it, it reads 10:50, though it should be a few minutes after midnight. And a few minutes later, the living room clock reads 7:23. Incidentally, the living room clock was placed there specifically for this episode. Normally the space is occupied by a painting.
