All the clocks in the movie say 6 o'clock
Did anyone notice throughout the movie all the clocks are right around 6:00? There's the scene near the beginning where the clock has stopped at 6. Then when she meets the Russian girl, it's 5 til 6, and she stays until 6:15. And at the end when the train is pulling out the clock says 15 til 6. There may be more scenes, but these are the ones that come to mind.
Knowing how meticulous De Sica is (and the fact that they mention the clock stuck at 6 in the beginning), I feel like there has to be some symbolism or deep meaning behind it. Does anyone have any ideas?
