At the end of the film during the ball when the clock begins to strike midnight, the first shot of the clock shows that it is 9:45 not midnight. That shot of the clock is taken from above the clock looking down at the palace entrance steps. Therefore the clock hands are pointing left on the camera shots (appearing to show 0945) though in fact they point straight up, i.e. 12 o'clock.

Did time past that fast?!
