http://home.tiscali.nl/~t876506/Multizones.html says
"As soon as the territorial waters of a nation is reached, the clock
is set to the local time of that (part of the) nation."


Probably interesting to know:
- What you referred to is my page (not interesting, but preliminary to the 
- The chapter about international waters is the result of a discussion on 
the TZ list a couple of years ago.
So, that information is in fact peer reviewed.
- The discussion was based on the renowned Bowditch publication The American 
Practical Navigator.

In the chapter mentioned above a table and an algorithm can be found, that 
can be used to find a kinda logical time for an uninhabited zone.

In my opinion: if an authority of an uninhabited island has defined a local 
time, the TZ database should have a zone designation, whether the island is 
uninhabited or not. The central place cannot be the largest inhabited place, 
but could be the geographic center of the island or a landmark of some kind 
(mountain top, abandoned station, etc.).
The mere existence of an ISO code, a FIPS code, internet TLD, whatever, 
should be of no concern to TZ.
