How many details should a time zone application give? It is sometimes difficult to find out in which time zone a certain city is situated. The TZ database files give good clues. If in any doubt, one has to find out the geographic coordinates and look on a map to find out in which zone these coordinates are situated. Some time zone servers and applications give somewhere between 50 and 10000 well known place names, but on this world there are at least 6 million locations with a name - 2 million in the US <http://geonames.usgs.gov/>, 4 million in the rest of the world <http://164.214.2.59/gns/html/index.html> (NIMA GEOnet). I produced a web page with a bit more detailed information about the provinces, regions, oblasty, aimags, island groups, counties and the like of countries with more than 1 time zone. Some countries were omitted because the TZ datafiles are specific enough. <http://home-4.tiscali.nl/~t876506/Multizones.html> Details: * USA: all states are mentioned, with a complete county list of states, divided by a time zone boundary. * Canada: only a bit more detailed than the TZ northamerica file; note the longitudes mentioned for Nunavut, Qu�bec and Ontario. * Mexico: complete list of all provinces. Names with diacritics. * Brazil. No more details than TZ southamerica file, but names with diacritics. * Russia: no more details than TZ europe file, but better transliterations of the regions in the Sakha republic. * Kazakhstan: complete list of all provinces with the old Russian names and the new Kazakh names. * Mongolia: complete list of all provinces, including names with diacritics. * Australia: no more details than TZ australasia file. * Indonesia: listing with many regions and islands. * Kiribati, Federated States of Micronesia: listings with many islands and some places. * Greenland: no more details than TZ europe file.
