I’m starting to feel that there is something fundamental that I am missing.
I can’t see any time setting here??
I can change weather, date, etc., but not the time. In real time the day is wrong, by the way, it’s indicating the 25th of April instead of… 3rd of May. Quite obviously the date on my computer is ok 
I am using a tour ( Italian Alps Tour 2021 » Microsoft Flight Simulator ), is it possible that by mistake/by choice they have blocked for some reason the time to this specific moment for these flights? It hasn’t been like this for the previous ones.
