It seems to not support 24h? When I see e.g. 17:35 I want to type 17:35 instead of 5:35. Probably because I very seldomly see 5:35 in real life! Interesting observation by itself, but slightly annoying that I have to convert to 12h for this game.
Now when people ask me what time it is and I say 1845, they often follow up with "What time is it really for normal people?"
Quarter 'til 19 of course.
