An update to the discussion about timezones at sea, discussed around 2000-01-05 (see tzarchive). The mentioned date I posted a list, with corrections by Gwillim Law. Recently I found a more or less official reference: Bowditch - The American Practical Navigator, Chapter 18 Time, Section 1806 Zone Time; National Imagery And Mapping Agency; 1995. More information, a table, an algorithm, a web link to Bowditch: see my Multizones web page: <http://home-4.tiscali.nl/~t876506/Multizones.html#iw> See also "The International Date Line" at the end of the TZ australasia file.
