Close to a 2006o?
by Stephen Colebourne Nov. 3, 2006

Nov. 3, 2006

Are we close to a version 2006o of the data? I am planning on releasing a new version of Joda-Time soon which includes the zone data. I know there have been a number of changes recently so I would like the release to include the up to date info if possible. On a more general note, is there a specific trigger for creating new releases of the tz database (eg. every month), or is it just created on demand? thanks for any info, Stephen http://joda-time.sourceforge.net

Nipigon and Atikokan
by Chris Walton Nov. 1, 2006

Nov. 1, 2006

Jesper, I don't know how much accuracy you need. I used a combination of the maps I sent you plus Garmin's Topo Canada to come of with some coordinates that I think are pretty close. Atikokan Township: Northern boundary: 48 degrees 50 minutes 0 seconds N Eastern boundary: 91 degrees 30 minutes 0 seconds W Southern boundary: 48 degrees 40 minutes 0 seconds N Western boundary: 91 degrees 45 minutes 0 seconds W If you wish to include Quetico Provincial Park it gets more complicated because it is not square. Nipigon Township: Northern boundary: 49 degrees 02 minutes 20 seconds N Eastern boundary: 88 degrees 14 minutes 0 seconds W Southern boundary: 49 degrees 00 minutes 0 seconds N Western boundary: 88 degrees 26 minutes 0 seconds W Note: the Township of "Red Rock" lies immediately south of the Township of Nipigon. My guess is that Red Rock has probably always followed Nipigon time. I have no proof and I don't wish to start making up history. Unless anybody has information Red Rock's time practices prior to 1974 we should keep "America/Nipigon" confined to Nipigon Township. -chris -----Original Message----- From: Chris Walton Sent: October 31, 2006 12:30 AM To: 'tz(a)elsie.nci.nih.gov'; 'jnorgard(a)prodigy.net.mx' Subject: RE: Canada details Jesper, I understand your confusion in trying to draw time zone boundaries for Atikokan and Nipigon. The "Township of Atikokan" and the "Township of Nipigon" are municipalities in Northern Ontario. Both townships have official boundaries and are officially recognized as municipalities by the province. The "town" of Atikokan is the built up area (townsite) within the Township of Atikokan. The "town" of Nipigon is the built up area (townsite) within the township of Nipigon. Before reading further, please understand that there are both "geographical townships" and "municipal townships" in Ontario. A "geographic township" is an area of land (usually rectangular in shape) that was given a name by the land surveyors many years ago. A "municipal township" is a municipality with some local political structure and generally a small population. The municipality of the "Township of Nipigon" lies exactly within the boundaries of the Nipigon geographic township. Total area is 109.65 square km with a population density of 17.9 people per square km. The north half of municipality of the "Township of Atikokan" is comprised of the geographic townships of Schwenger and Freehorn. The south half of is comprised of an area that was not surveyed in the original Ontario land surveys. Total area of the municipality is 316.81 square km with a population density of 11.5 people per square km. Note: there isn't (and never was) a geographic township named "Atikokan". The time zone boundaries for both Atikokan and Nipigon should presumably follow the municipal township boundaries. The best way to get the boundaries would be from paper copies of the federal 1:50000 topographical maps. Here are some online maps that give a general idea of the areas involved: Atikokan: Look for the black square near the east end of the Rainy River district. http://www.mah.gov.on.ca/userfiles/page_attachments/Library/1/1652085_E_200… Here is a more detailed map with some latitude and longitude markings. The Township of Atikokan is the larger of the two black squares in the center of the map. http://crownlanduseatlas.mnr.gov.on.ca/tilemaps/pdfs/_920485.pdf Nipigon: Look for the black rectangle south of Lake Nipigon http://www.mah.gov.on.ca/userfiles/page_attachments/Library/1/3519577_E_200… Here is a more detailed map with some latitude and longitude markings. The Township of Nipigon is near the bottom of the map. http://crownlanduseatlas.mnr.gov.on.ca/tilemaps/pdfs/_890490.pdf If you are making a time zone map you have to decide whether to lump Quetico Provincial Park in with Atikokan. Quetico is a large wilderness park. At 4758 square kilometres it is more than ten times the size of Atikokan itself. It is mostly used by canoeists in the summer and cross country skiers in the winter. The head office for Quetico is inside the town of Atikokan. The park staff uses Atikokan time for official purposes. Campers, canoeists, skiers, etc. can use what ever time they wish. Also, if you are creating time zone maps for all of Canada, please be aware of recent changes in Quebec time legislation. If I understand the new legislation, the time zone boundary will no longer follow the 63rd meridian starting next year. See my notes in: http://www3.sympatico.ca/c.walton/canada_dst.html Let me know if you need any more info. If I come across any better maps I will let you know. -chris -----Original Message----- From: Oscar van Vlijmen [mailto:ovv@hetnet.nl] Sent: October 30, 2006 5:29 PM To: tz(a)lecserver.nci.nih.gov Subject: Re: Canada details > From: Jesper Norgaard Welen > Date: Mon, 30 Oct 2006 00:43:39 -0600 > Subject: Strange historic timezone in Nigeria > As a side-question, I'm trying to determine a meaningful area for the > timezones Atikokan and Nipigon, it seems to me that they would be > small, like a US county for instance, but I can't find anything about > it.

West Australia DST pushing forward
by Jesper Norgaard Welen Nov. 1, 2006

Nov. 1, 2006

West Australia has made a step further to implementing DST, the lower house approved the DST bill, but to go ahead the bill must also be passed in the upper house. In the meantime rhetoric flies high, DST can save lives, the upper house should be abolished if the DST bill is not passed etc. : http://origin.theaustralian.news.com.au/story/0,20867,20682208-29277,00.html Also a sincere thanks to Chris Walton for the "Canada details", I will look into that, but it looks good at first sight, just what I needed. And an apology for the ill-thought-through question about Niger (not Nigeria!), I hadn't even seen the comment in the 'africa' file about the double use of WAT for GMT-1 and GMT+1, and besides I could have confirmed with astro.com that Shanks also agree about the GMT-1 for Niger in the period specified.

Strange historic timezone in Nigeria
by Jesper Norgaard Welen Oct. 31, 2006

Oct. 31, 2006

Hi, tz emailing list I have stumbled over a peculiarity in the historic data about Nigeria, the africa file contains: Zone Africa/Niamey 0:08:28 - LMT 1912 -1:00 - WAT 1934 Feb 26 0:00 - GMT 1960 1:00 - WAT Since the timezone abbreviation 'WAT' is the same seemingly for both GMT-1 and GMT+1, my suspicion is that it should rather be Zone Africa/Niamey 0:08:28 - LMT 1912 1:00 - WAT 1934 Feb 26 0:00 - GMT 1960 1:00 - WAT which would make more sense from the lunar mean time value ... As a side-question, I'm trying to determine a meaningful area for the timezones Atikokan and Nipigon, it seems to me that they would be small, like a US county for instance, but I can't find anything about it. It seems they most be within the larger areas Rainy River district and Thunder Bay district, but how would it look on a map? Regards, Jesper

Chile DST history
by Jesper Norgaard Welen Oct. 31, 2006

Oct. 31, 2006

The page http://www.worldtimeserver.com claims that Chile starts DST this Sunday 8.th. of October at 1:00 so I got interested in if we have the information right concerning Chile. This made me revise the information in the tz database, which lead to the page http://www.shoa.cl which represents the oficial timekeeping of the armed forces of Chile, which in turn is the only authority on time setting matters in Chile since 11.th. of January 1966 according to decree No. 25 of that year. CIA factbook says on page http://www.cia.gov/cia/publications/factbook/geos/ci.html that DST starts second Sunday in October, ends Second Sunday of March. But according to the official page it is really Second Saturday of October at 24:00 and Second Saturday of March at 24:00. 2006 happens to be a year where these two rules get to different results, in fact DST begins in Chile in 2006 Saturday 14.th. of March at 24:00, according to one of the Chile web pages. In tz database, file southamerica says: # From Paul Eggert (2002-10-24): # <http://www.shoa.cl/shoa/faqhoraoficial.htm> gives many details that # disagree with the following table, but we haven't had time to compare them. As far as I see it, this is the maximum authority of time setting in Chile, which should supersede tz database, Shanks, IATA etc. If you disagree on this point, please forward good arguments. Therefore I recommend the following changes to the tz database. I took the time to check out in detail what the differences are from this source compared to tz database, based on the page http://www.horaoficial.cl/horaof.htm which contains timezone and time history in Chile since 1884. Here are the results if you apply those to the tz database (I might have made mistakes, since there are plenty of differences): # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Chile 1927 1931 - Sep 1 0:00 1:00 S Rule Chile 1928 1932 - Apr 1 0:00 0 - Rule Chile 1946 only - Aug 27 4:00u 1:00 S Rule Chile 1947 only - May 21 2:00u 0 - Rule Chile 1968 only - Nov 2 4:00u 1:00 S Rule Chile 1969 only - Mar 29 3:00u 0 - Rule Chile 1969 only - Nov 22 4:00u 1:00 S Rule Chile 1970 only - Mar 28 3:00u 0 - Rule Chile 1971 only - Mar 13 3:00u 0 - Rule Chile 1970 1972 - Oct Sun>=9 4:00u 1:00 S Rule Chile 1973 only - Sep 29 4:00u 1:00 S Rule Chile 1972 1986 - Mar Sun>=9 3:00u 0 - Rule Chile 1974 1987 - Oct Sun>=9 4:00u 1:00 S Rule Chile 1987 only - Apr 12 3:00u 0 - Rule Chile 1988 only - Oct Sun>=1 4:00u 1:00 S Rule Chile 1988 1989 - Mar Sun>=9 3:00u 0 - Rule Chile 1989 only - Oct Sun>=9 4:00u 1:00 S Rule Chile 1990 only - Mar 18 3:00u 0 - Rule Chile 1990 only - Sep 16 4:00u 1:00 S Rule Chile 1991 1996 - Mar Sun>=9 3:00u 0 - Rule Chile 1991 1997 - Oct Sun>=9 4:00u 1:00 S Rule Chile 1997 only - Mar 30 3:00u 0 - Rule Chile 1998 only - Sep 27 4:00u 1:00 S Rule Chile 1998 only - Mar Sun>=9 3:00u 0 - Rule Chile 1999 only - Apr 4 3:00u 0 - Rule Chile 1999 max - Oct Sun>=9 4:00u 1:00 S Rule Chile 2000 max - Mar Sun>=9 3:00u 0 - # IATA SSIM anomalies: (1992-02) says 1992-03-14; # (1996-09) says 1998-03-08.

It seems that the Chile web page claims that it stopped in 1928, but it doesn't mention a decree about that. Note (2) The DST employment in 1946-1947 was decreed only for the central zone (whatever that is, but surely including Santiago), not for the rest of the country. But since this happens before our cutoff date of 1970, there is no need to make an extra timezone. Note (3) Since one of the IATA anomalies were agreeing with the Chile page, I deleted that from the commentary. I also did not put commentary for if the above changes are accepted (like "Jesper Norgaard wrote ..."), I will leave that happily to whoever might implement it in a coming version of the tz database.
