How does it use it?
And what is this "time" of yours? Are UTC, TAI, a zone
time - times, or are they something else?

Modelled by a rock, or modelled by us?
Who or what is using "time" concept  here?
??
Natur is not a modell, but the thing, which we like to modell.
Modells are necessarily simpler than the real thing, because otherwise they are simply unusable.

So, are UTC, TAI, zone times - times? Or
are they something else?
Time zones are something else.
a 'time domaine' is a set of places, where the same clocks can be used and permanently show the same time, once they are synchronized properly.
This is the case for all clocks around the Earth at the same hight above mean sea level.
Time zones are just for convinience, to allow same time of sunrise.
But that makes clocks show different times and disallows synchronization.
