I think this would be awesome, but worlds like San Myshuno are based off of Tokyo and New York City, which have quite different time zones , and consistency across the game will be broken.
I don't know if daylight changes in different seasons where it's darker for longer in winter and lighter in summer, if this isn't already in the game then could they add it (Btw im a builder and I dont use gameplay that often)
I do believe that time in game does need to be altered in ways that improve realism, if there was a new option were we can choose slower options, not to slow down the gameplay but just so time passes slower as I believe it goes too fast.
