People need to understand that chronologically CTMEOY happens AFTER the point were are in the manga right now. This is actually the very first time Hayate sees this clock in canon.
I know CTMEOY happens after all this. The plot hole is that the clock shouldn't even be there at Mikado's mansion. It should be in the USA (since it got taken by the police when Shin died) and that's where Hayate first saw it anyway.
