Time zone boundaries for multizone countries
by Oscar van Vlijmen Oct. 19, 2003

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, Québec 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. Corrections are welcome! Oscar van Vlijmen 2003-10-18

Brazil zoneinfo corrections.
by Rodrigo Severo Oct. 16, 2003

Oct. 16, 2003

Dear list, First of all, I would like to apologize for the confusion I might have caused with my previous emails. The corrections for the brazilian rules and zones I sent where already included in tzdata. I hope this haven't created any problems. Now I send another set of corrections for the brazilian tz data. I have just finished a full review of its rules and zoneinfo from the decrees list at the Brazilian National Observatory (main source of time info in Brazil, the same source already used by previous authors) with the following problems identified and corrected: 1. The effects of decrees 52700 (1963-10-18) and 53071 (1963-12-03) weren't correctly represented by the data as what they really have done was to make a set of states start DST at 1963-10-23 00:00 and the rest of the country to start DST at 1963-12-09 00:00. Fix: change the rule and all affected zones (almost all of them). Also had to create a new Brasilia zone to acomodate the diferences between Sao_Paulo zone and Goias (GO), Distrito Federal (DF), Parana (PR), Santa Catarina (SC), Rio Grande do Sul (RS). 2. The starting time of DST for 1966 was wrong as the 57843 decree stablishes that DST shall begin at 1966-03-01 01:00 and on 1st of March 00:00 from 1967 and on. Fix: new rule for DST start at 1966. 3. Decree 1252 (1994-09-22) defines that the previous states minus AM _AND_ MT states would have DST during 1994/1995 summer. The author of the previous comment probably relied on the Brazilian National Observatory resume of the decree - which is wrong - and not on the actual decree itself (also available at the Brazilian National Observatory site). Fix: America/Cuiaba zone fix. 4. Fernando de Noronha island had wrong timezone info as it should include all DSTs for the Pernambuco state after 1988 as Fernando de Noronha island became part of the Pernambuco state after the brazilian contitution of 1988. If someone has any doubt about it, please check decree 96676 (pre 1988) which clearly includes Pernambuco state, Fernando de Noronha and Atlantic islands. Compare with decree 98077 (pos 1988) which clearly includes Pernambuco state and Atlantic islands (doesn't mention Fernando de Noronha because it already mentioned Pernambuco). Fix: Include all DSTs for Pernambuco after 1988 and create new zone Atol_das_Rocas for the atlantic islands. Maybe this new zone should be called Brazilian_Atlantic_Islands? Too long? 5. America/Sao_Paulo zone had a DST during the whole 1964. I can't see where it came from. There is no decree mentioning it. Fix: Remove it spurious zone info. The patch I am including here is based on the data available at ftp://elsie.nci.nih.gov/pub/ dated 10/06/2003 01:41:00 PM. If someone has any comments on these changes, please send a copy to my personal email as I not sure if I am already subscribed to this list.

Hi, I have noticed that I have not received any email update about TZ changes for a while but have not paid much attention until I ran into a problem with Brazilian time zone changes for 2002 and 2003. After looking at the web for sometime I realize that the archive might have gone forever. The TZ archive has been very valuable to my work, I want to thank all the people who were diligently keeping the archive up to date. I'm very curious as to what happened to the emails and If you have any information for the where about of the archive or any other useful sites, please let me know. Regards, Ren Wong

Decree on Brazilian Summer time
by Paulo Alexandre Pinto Pires Sept. 26, 2003

Sept. 26, 2003

Hello. The official decree was finally issued and can be get at <https://www.planalto.gov.br/ccivil_03/decreto/2003/D4844.htm>. However, it contains a great infelicity: it clearly states that summer time is to end at 2004/02/14 00:00. That would be, for the strict reader, at midnight from Friday to Saturday. I am affraid that they really mean midnight from Saturday to Sunday, which is consistent with previous editions of summer time. What are we to do? -- Pappires ...

Hello! The tz database states +9 for Mongolia, but +8 is correct: Time Differences Most of Mongolia is 8 hours ahead of GMT. However, the three western aimags of Khovd, Uvs and Bayan Ulgii are GMT+7. Mongolia no longer puts forward its clocks by 1 hour in the summer months. Found on: http://www.mongoliatourism.gov.mn/fackpack.html Many greetings from Dani

Hi, When you must have an official confirmation of the Brazilian government on the beginning and the end of the summer time 2003/2004, and which the states will go to have the summer time? It starts day 19 of October of 2003 and goes until the 14 of February of 2004. When you go you are bringing up to date the southamerica archive?

proposed changes to zic and zdump
by Olson, Arthur David (NIH/NCI) Sept. 9, 2003

Sept. 9, 2003

Below are changes to zic and zdump code and documentation to cover "--version" options; there's also a zic buglet fix. If folks are happy I'll incorporate these in the next release (due around the last Sunday in October, after any data changes have arrived). I'm deferring the business of putting identifiers into the output of zic to identify the source of the output. There are two areas to ponder: 1. An output file depends on the version of zic that was used to create it as well as one or more input files (certainly the file that contains the relevant "Zone" line, but also perhaps a leap second file and--potentially at least--one or more files that contain "Rule" lines. What information is sufficient? 2. Does the information need to be reflected in the header of the output file, or is it sufficient to just append the information to the end of the generated output? --ado ------- zic.8 ------- *** /tmp/geta13698 Thu Aug 21 20:27:02 2003 --- /tmp/getb13698 Thu Aug 21 20:27:02 2003 *************** *** 4,9 **** --- 4,12 ---- .SH SYNOPSIS .B zic [ + .B \-\-version + ] + [ .B \-v ] [ .B \-d *************** *** 44,49 **** --- 47,55 ---- .PP These options are available: .TP + .BI "\-\-version" + Output version information and exit. + .TP .BI "\-d " directory Create time conversion information files in the named directory rather than in the standard directory named below. *************** *** 411,414 **** /usr/local/etc/zoneinfo standard directory used for created files .SH "SEE ALSO" newctime(3), tzfile(5), zdump(8) ! .\" @(#)zic.8 7.19 --- 417,420 ---- /usr/local/etc/zoneinfo standard directory used for created files .SH "SEE ALSO" newctime(3), tzfile(5), zdump(8) ! .\" @(#)zic.8 7.20 ------- zic.c ------- *** /tmp/geta13738 Thu Aug 21 20:27:22 2003 --- /tmp/getb13738 Thu Aug 21 20:27:22 2003 *************** *** 1,8 **** ! #ifndef lint ! #ifndef NOID ! static char elsieid[] = "@(#)zic.c 7.107"; ! #endif /* !defined NOID */ ! #endif /* !defined lint */ #include "private.h" #include "locale.h" --- 1,4 ---- ! static char elsieid[] = "@(#)zic.c 7.110"; #include "private.h" #include "locale.h" *************** *** 446,452 **** static void usage P((void)) { !
