Most concepts seem to have a particular deity unambiguously associated with them. But Time, fundamental as it is, does not—in the Greek pantheon, for example, there is Chronus, later conflated with Cronus; and several different versions of the Horae; and Aeōn.
Are there any other Greek or Roman deities specifically associated with the passage of time, or the manipulation of time? And were any specifically known as "the god of Time"? (I'm curious mostly about time in the sense of χρόνος/tempus, but deities associated with vicis, καίρος, or αἰών also qualify.)
