It appears that the Apple TV can’t establish a good connection with a network time server to get date and time from the internet. In case the issue is on your home network, try restarting both the router and the Apple TV box to refresh the connection. Verify that port 123 UDP isn’t blocked on your home network by a firewall setting of sorts.
