I think there's some confusion here.
The mission will run all weekend long. It's starting early for those fellas on the other side of the Earth
But the mission will rotate/recycle/start over after a certain amount of time. If the blues don't get all their objectives in a 4 hour window, reds will win and the mission/map will reload. On the same front if the blues destroy all their objectives, the mission will end with blues winning (but it will start over again) So basically, it will repeat this all weekend long. There's no particular show up time that everyone needs to be there for. It's just done this way so everyone that wants to throughout all the time zones will get a crack at it.
