Given this practice, I concur that we can accept local time to be
well-defined for an uninhabited location.  Whereas for inhabited
locations we attempt to track what the inhabitants' wall clocks show,
for uninhabited locations that have territorial waters we'd have to
track what ships in those waters (that accept the use of such local time)
set their clocks to.  That's the closest available equivalent principle.

I don't think this means we should entirely delete the reference to
population in the Theory file.  Population is still a relevant qualifying
feature.  We've identified a second qualifying feature (ships visiting
territorial waters), which should be explicitly discussed alongside

We'd also need to pick a location that has a well-defined and distinctive
name, so it'll need to be a clear geographical feature, not just an
arbitrary point.  An entire island or a station would likely be top
choice.  Necessarily decided case-by-case, of course.
