I just watched 1917 (2019) and most of it seems to be in real time (which gave the movie its tension, but also made it somewhat grueling at times).
The only scene I caught where time passes off screen was one where the main character is shot at, he falls backwards downstairs and is unconscious - when he comes to it's now dark out (at the start of that scene it was still light out). I couldn't find any other "breaks" to suggest time passed as the action following the main character seemed continuous.
However, based on the plot points that the characters left on a mission when it was daylight, a night passes and the mission is concluded during daylight - apparently at least 12 (or up to 24 hours) passed. I think early in the film they said something about it taking 6 hours to get from one point to another without running into any obstacles... but they ran into plenty of obstacles.
