Cats are incredibly good at knowing the time if it's the same time they probably already know and are thinking "Whatever food giver make those thumbs dance".

Mine gets treats at 9pm and she knows almost exactly when it's 9pm maybe a 1 minute deviation. This is without an external cues. She sits there waiting for me if I forget.

I can confirm that cats knows the time. My cats come everyday 3:30 pm sharp signaling that is food time. They are outdoor cats and often go wandering but by 3:30 they are back home.
