Why is Cronos the god of time?

I'm curious, why is Cronos, the deity we often associate with the ticking of the clock and the inexorable flow of time? Could it be due to the ancient myths surrounding him, where he was portrayed as swallowing his children, symbolizing the continuous cycle of life and death? Or is it because of his role in Greek mythology, where he represented the passing of generations and the change of eras? It seems like a profound concept to link a deity with time, considering its abstract nature and the way it shapes our existence. I'm eager to understand the reasons behind this association and how it fits into the broader mythology and cultural understanding of time.
