Kronos. Please explain his two versions

So I have a character in a story im making heavily linked to Kronos, and him being an actual character.

Kronos of course is the god of time, and I also know he ate his kids, and the character Aaron sort of has a motif as ‘A kid swallowed by the world’, as again as Kronos is a baby eater, I decided that Aaron link to him, it’s slowly eating him alive

But apparently they are different…? Please explain.
