I think the point is that if we're standardizing a lunar time, it should be done with as much precision as possible. Kind of like how we have very precise benchmarks for what our units of length are in terms of fundamental properties.

Personal computers don't care much about timing down to the nanosecond, but scientific pursuits often need that level of precision, standardizing timing with high precision would make it easier to perform experiments that depend on time correlated comparisons across the lunar surface.

It's still a weak case in my opinion, things can always be refined later.
