This is part of the Frank said feature. You can see more here.
We had just gotten home from the airport when Frank was jumping back and forth from the kitchen to the bedroom…
Me: What are you doing? Is something wrong?
Frank: 1056, 1056, 1156, 1056, 1156, 1056
Frank: The clocks! That room is in the future!
Frank: [deep sigh] Gnight, I’m going to the future now.
