Kronos is Clockwork
Kronos is Clockwork He gets the memories of being Clockwork when he is still Kronos, before the eating of Hestia. So he knew what would happen. And it didn't matter, he would lose, at least if he lost he would wake up in the Ghost Zone and meet Danny later.
So Clockwork-Kronos decided not to eat his children, but just to ignore them. From Hestia to Zeus, he didn't care much for them. He knew they would always "ursup" him because he knew their future.
And years later, Kronus gave up his throne and left.
Once in the Ghost Zone, after years. He turned back into clockwork, looked at the timelines and was the guardian of them.
Until he met Danny again, and Clockwork was overjoyed to see him. Even if the Dan fiasco was there again.
Clockwork took care of the young hero and raised him.
Clockwork/Kronos watching Danny: "Everything is the way it's supposed to be.
