The most pressing problem with [lunar timing an location):
what are they going to call the lunar equivalent of the geoid?
The 'loonoid', perhaps?

A more pressing problem is: which timezone(s) will be used?
With a ~ 700-hour "day" it's not clear what to do....

That has been solved for the time being: no time zones. [1]
No leap seconds either, all clocks in space refer to TAI,
or to coordinate times that are linked directly to TAI.

Timezones have nothig to do with time.
Timezones are used to make the numerical value of the time of the
sunrise at least somehow equal for all places on the Earth' surface.
As Moon is not located on Earth' surface, the man in the Moon has other worries than our time zones.
Because the 'day' is quite long on the moon, the 'hours' could be as well.
Or they use more 'hours' there, if they want to.
But that isn't related to the nature of time, because the sunrise istn't
time neither.

If time is what a clock says, and the sun says it's sunrise on the sun
clock, it's time is sunrise. Am I wrong?

The sun clock sits on the earth not on the sun. They are called
sun-clock sundial.
