math people question!

I keep meaning to ask someone-- is there a word for number systems like time that are in base 10, but have the next unit skip at 60 or whatever instead of 100? In my head I call it " base 10, big base 60," but I'm pretty sure this is just something I came up with in elementary school when I was learning about the concept, and I don't know if I've ever heard a real term for the phenomenon.
