Event Times

Hey I love the events that we often see by Zwift. But I do not understand why there would be more times for each event. In the latest 3 stage event, the first stage has a 7:00pm event that worked really well for me. But the next 2 stages, I have to do at 9:00am at the latest. The next one is at mid-night… I know we are from all around the world, but it would seem to make sense if that is the case to see event times that work for everyone/
