Is it possible to set the game time to match the local time? It’s a bit odd looking at nighttime on the screen when the sun is streaming in through the window.
It is also nice to have a sunny day on Zwift when it’s actually dark outside, I wouldn’t want it to be dark all the time when I’m riding at night either.
This is what I found.
Night lasts about 12 minutes, day lasts about 20-25 minutes, so a full cycle takes 30-40 minutes.
