Idaho tz correction

In reply to: [tz] Idaho tz correction Ian Abbott abbotti at mev.co.uk Tue May 22 11:12:18 UTC 2012 .... I guess we'd want to change the comment for Southern Idaho (America/Boise) as well, replacing "the southern quarter of Idaho county" with "the part of Idaho county lying south of the Salmon River".) Though looking at the map, the river meanders a bit so that some of the portion described above as lying south of the Salmon River is actually north of part of the river and south of another part of the same river! Reply: The law says that the "main channel of the Salmon River" the boundary is. US Code of Federal Regulations, Title 49 (Transportation), Subtitle A (Office of the Secretary of Transportation), Part 71 (Standard Time Zone Boundaries). See paragraph 71.9. Oscar van Vlijmen

This image: www.discogs.com/Frank-Zappa-Sheik-Yerbouti/release/429613 demonstrates the local time zone border. The Nevada/Idaho state line is the official border, while the portion of the magenta that descends south into Nevada is the local unofficial observed time. Cheers, Steve Jones

I suggest to keep "most of Nevada", but to amend the comments for the Nevada part that is on Mountain time, so the exceptions are only mentioned at one place.

Here is an image that shows Idaho County, Idaho City, and a magenta line indicating the path of the time zone border in that area: <http://ontimezone.com/images/idahocounty.gif>http://ontimezone.com/images/idahocounty.gif It might be be more accurate to say "northeastern three-quarters of Idaho county", given the portion of the America/Boise rule which juts northwards to the west of the Salmon River.

Theory - proposal to delete the reference to population
by OvV_HN May 21, 2012

May 21, 2012

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

Do you have any source, international treaty or so, to support your claim? If they get on land, would that change your claim, or would they observe what has been reported as official time for HM by Australian agencies? -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com/

Uzbekistan - insufficient location desciption
by Tobias Conradi May 18, 2012

May 18, 2012

tzdata2012c/asia no location comment except # Uzbekistan for Asia/Samarkand Asia/Tashkent Also no other comment, telling where the Uzbekistan info comes from. tzdata2012c/zone.tab Asia/Samarkand west Uzbekistan Asia/Tashkent east Uzbekistan No definition for "West Uzbekistan" or "East Uzbekistan" found. Trying to improve: Asia/Samarkand per definition includes Samarkand Province, where Samarkand is located. "west Uzbekistan" if only contrasted by "east Uzbekistan" and using the map at http://en.wikipedia.org/wiki/Provinces_of_Uzbekistan likely additionally refers to Karakalpakstan, Xorazm, Buxoro, Navoiy Uncertain remain Jizzax (north east), Qashqadaryo (south) and Surxondaryo (south). But since the two southern country subdivisions, if looked at as one unit, border Samarkand, they may be included in Asia/Samarkand. This leaves five provinces, with Jizzax six, for the Asia/Tashkent. If that is the case zone.tab could be improve by Asia/Tashkent east Uzbekistan (Andijon, Fergana, Namangan, Tashkent, Sirdaryo [, Jizzax]) -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com/
