This is, of course, pure speculation.
When I think about Time, a recurring theme that I find is cycles. A year is a full cycle around the Sun. A day is full rotation around the Earth's axis. Since 1967, a second is defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom. In simpler terms, it is a specific (and large) number of electron cycles.
Intuitively, this makes sense. After all, if nothing at all ever repeated, there would be no numbers because there wouldn't be two of anything, let alone more. So it would make no sense to say: 2 minutes please!
