Your dog has been staring at you for the last 20 minutes. Not because they love you. Because they know exactly when dinner happens and you are currently 4 minutes late.
Animals have this uncanny ability to track time without a single device. No phone, no watch, no alarm blaring something awful at 6am. They just know. And honestly, the precision is a little embarrassing when you compare it to most humans stumbling through their morning routine like a confused roomba bumping into walls.
