Sometimes when my wife and I Zwift together, one of us is riding in the daytime and the other is riding in the night. We have double checked our profiles for location, we are riding at the same time, we are riding in the same room and on the same brand trainers. Any idea why this is? Could it just be a random time of day by Zwift?
As I understand it, the Zwift day/night cycle lasts around 40 minutes. Depending on what time you join a particular Zwift server, you will experience the cycle that the server is running.at that moment
If another rider joins you it may not be from the same server so the day night cycle is at a different point :)
I believe there has been talk of syncing servers’ day/night.
