In reply to: [tz] Theory - proposal to delete the reference to population Tobias Conradi tobias.conradi at gmail.com Fri May 18 18:20:39 UTC 2012 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." Reply: Probably interesting to know: - What you referred to is my page (not interesting, but preliminary to the next). - 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. Oscar van Vlijmen
