Yes that’s the whole reason that it exists on the site now. What time it is in-game is now synced for everyone. So if when the Alpha test starts it says it is 13:00 on the website, when everyone logs in it will be daytime for everyone. And everyone will experience sunset at the same time so you can all collectively bask in it together
We decided to do the “5 hours real-time = 24 hours in-game” thing so that if you (for example) always play in the evenings from 7 - 9 PM, you won’t always get the same time of day. Instead you’ll get a variety.
