I am trying to connect my apple tv to a wireless connection in a hotel room and all it shows is setting date and time, what should I do?

Welcome to the Apple community.

There probably isn't a lot you can do, since the router settings will be beyond your control. Many such services in hotels and the like, use a system whereby you need to login through a webpage, since the Apple TV cannot display webpages, there is no way around this. You would probably be best asking at reception if this is the case.
