We see then Arashi get up in the middle of the night, so it could easily be midnight...but then he reaches the station and it's daylight, and the kid is in his car, even. Moreover, when the troops enter, a clock inside the building points 2:10.

Other mistake: When Bemular holds submarine 516 in its mouth, submarine 516 becomes submarine 16. (00:18:40)
