daylight-saving news from UCEI, WA, NZ, WY, TERiX
by Paul Eggert Feb. 1, 2007

Feb. 1, 2007

Some recent news about daylight saving time: Ryan Kellogg and Hendrik Wolff of the University of California Energy Institute have published a paper "Does Extending Daylight Saving Time Save Energy? Evidence from an Australian Experiment", CSEM WP 163 (January 2007) <http://www.ucei.berkeley.edu/PDF/csemwp163.pdf>. Their brief answer is "no". They report that the Australian experiment with DST during the 2000 Olympics did not decrease overall electrical consumption, but it did change usage patterns leading to a higher morning peak load. Western Australian Nationals leader Brendon Gryllis says his party will submit a private member's bill next month, calling for a referendum before October 31 to repeal daylight saving time in Western Australia. Nelson, NZ city councillor Mark Holmes and United Future Party leader Peter Dunne have gathered a petition with 10,000 signatures to extend daylight saving time in New Zealand by three weeks. <http://www.newstalkzb.co.nz/newsdetail1.asp?storyID=110957> The Wyoming Senate's Corporations, Elections and Political Subdivisions Committee voted 3-2 against exempting Wyoming from daylight saving time. In a recent poll 41% of Wyoming's inhabitants want to repeal daylight saving, and 44% want to keep it. <http://www.billingsgazette.net/articles/2007/01/18/news/wyoming/55-time.txt> <http://www.billingsgazette.net/articles/2007/01/17/news/wyoming/38-time.txt> Various companies have announced support for the US daylight-saving time changes in their software, or in older versions of other people's software. My favorite was TERiX, which announced free patches for Solaris 2.5.1 through 2.7, for customers who don't want to bother to run 'zic' themselves.

Canada (2007)

Jan. 31, 2007

For anybody wishing for info on new Canadian daylight saving legislation, I have been trying to keep the following page up to date: http://www3.sympatico.ca/c.walton/canada_dst.html The web page is full of links to various government news releases and legislation. All of Canada with the possible exception of Nunavut will be extending daylight saving this year to match the United States. Below is an extract of some of the more important hyperlinks from the web page listed above. City of Lloydminster The "Lloydminster Charter" which defines time for the city of Lloydminster on both sides of the Alberta/Saskatchewan border will likely not be amended prior to March 11. Regardless, the Senior Director of Corporate Affairs e-mailed me last year to say that Lloydminster would extend daylight saving to match Alberta. British Columbia News release: http://www2.news.gov.bc.ca/news_releases_2005-2009/2006AG0014-000330.htm Alberta News release: http://www.gov.ab.ca/acn/200602/193862BFE321E-A3D2-C519-F34B3EE936DA55E2.ht… Daylight Saving Amendment Act assented to March 23/2006: http://www.qp.gov.ab.ca/documents/spring/CH03_06.CFM?type=htm Saskatchewan No official announcement but most of Saskatchewan does not observe daylight saving time. The small area outside the Lloydminster city limits is governed by the Saskatchewan Time Act and will most likely follow Lloydminster even if the act is not updated. Manitoba News release: http://www.gov.mb.ca/chc/press/top/2005/11/2005-11-02-06.html Manitoba Official Time Amendment Act assented to December 8/2005: http://web2.gov.mb.ca/laws/statutes/2005/c05305e.php Ontario News release: http://www.attorneygeneral.jus.gov.on.ca/english/news/2005/20051020-dst.asp Ontario Regulation 111/06: Variation of Time in Effect filed April 12/2006: http://www.e-laws.gov.on.ca/DBLaws/Source/Regs/English/2006/R06111_e.htm Quebec News release (French): http://communiques.gouv.qc.ca/gouvqc/communiques/GPQF/Decembre2006/07/c5073… Legal Time Act assented to December 12/2006: http://www2.publicationsduquebec.gouv.qc.ca/dynamicSearch/telecharge.php?ty… New Brunswick News release: http://www.gnb.ca/cnb/news/pre/2005e1737pr.htm Act to Amend the Time Definition Act assented to June 22/2006: http://www.gnb.ca/0062/acts/BBA-2006/Chap-19.pdf Nova Scotia News release: http://www.gov.ns.ca/news/details.asp?id=20060425004 Royal Gazette with regulation 62/2006 on page 244: http://www.gov.ns.ca/just/regulations/rg2/2006/ma1206.pdf Prince Edward Island Act to Amend the Time Uniformity Act assented to May 24/2006: http://www.assembly.pe.ca/bills/pdf_chapter/62/3/chapter-41.pdf Newfoundland and Labrador News release: http://www.releases.gov.nl.ca/releases/2007/mpa/0118n03.htm Act to Amend the Standard Time Act assented to Dec 12/2006: http://www.hoa.gov.nl.ca/hoa/bills/Bill0634.htm Yukon News release: http://www.gov.yk.ca/news/2006/06-164.html O.I.C 2006/127: Daylight Saving Time ordered July 13/2006: http://www.gov.yk.ca/legislation/regs/oic2006_127.pdf Northwest Territories News release (Press "Daylight Savings Time Change" to see pop-up): http://www.exec.gov.nt.ca/currentnews/currentPR.asp?mode=archive It is not clear if legislation has actually been drafted. Nunavut No formal announcement has been made from the Nunavut Government. The premier of Nunavut claimed in August of 2005 that he did not want to touch the issue; nothing more has been heard since. It is likely Nunavut will eventually follow the rest of the country but there will certainly be confusion on March 11/2007 if no formal announcement is made. Currently the TZ database and Microsoft make assumptions that Nunavut will follow the rest of the country. If you find errors in the web page listed at the top of this e-mail or in this e-mail itself, please let me know. I may be somewhat unreachable for the next few days so forgive me I don't immediately respond to e-mail. -chris

FW: Looking for US timezone data files

Jan. 31, 2007

I'm forwarding this message from Michele Teifke, who is not on the time zone mailing list. Those of you who are on the time zone mailing list should direct replies appropriately. Michele: what you've downloaded is the source code for the time zone compiler and source files; you get to run the source files through the compiler to create the binary files that actually get used by operating systems. Note that the "backward" source file is what's processed to create binary files such as "US/Central". Mailing list folks: this introduces a more general question--is there any open-to-the-public collection of time zone binary files? --ado ________________________________ From: Michele Teifke [mailto:mteifke@myrio.com] Sent: Wednesday, January 31, 2007 1:34 PM To: tz(a)lecserver.nci.nih.gov Subject: Looking for US timezone data files I downloaded the timezone data files from the link you gave on this page. But the set of files is incomplete, it does not contain the US subdirectory of data files. i.e.: US/Pacific, US/Central. Could you tell me if there is a place I can download a complete list of these files. thanks, Michele

DST rules for Istanbul, Turkey
by Nirav Jk Vora Jan. 30, 2007

Jan. 30, 2007

Hi, I am Nirav from the Java Technology Centre, IBM. I am working for the L3 team here. Sometime back, one of my colleagues Amar Devegowda, had mailed regarding updation of the DST rules for Istanbul,Turkey. Actually as per the current rule that is being used in the JVM Daylight saving was supposed to start at 3.00AM . But as per the latest rule from the below link, Daylight timings start from 1.00AM. We were asked to provide an official link where these changes were stated. I hope this link will serve the purpose so that the database can be updated with the latest DST rules for Istanbul. http://wwp.greenwichmeantime.com/time-zone/europe/european-u nion/turkey/ Please do contact me for any further queries that may be there.

Mexico DST news
by Jesper Norgaard Welen Jan. 23, 2007

Jan. 23, 2007

I have not found any single news item that any political decision has been taken whether to follow in Mexico the new US DST rule (that is a month longer than the old one). After the legal fight between former president Vicente Fox and former Mexico City mayor Manuel Lopez Obrador it was clarified in supreme court that DST issues remain with the Congress. On the page of the Energy Saving Trust of Mexico http://www.fide.org.mx/servicios/verano.html it says that DST (spanish: horario de verano) will start in 2007 Sunday 1.st. of April, and end Sunday 28.th. of October (old US-style DST). In the following page http://www.cenam.mx/HoraExacta.asp there is an explanation of that USA will change their schedule to be from Second Sunday of March at 2:00 until First Sunday of November at 2:00 while Mexico will continue with the old DST that is from First Sunday of April at 2:00 to Last Sunday of October at 2:00. However, I'm willing to bet a dinner on that Mexico will follow US from one of these two scenarios: (a) A hasty just-in-time decision puts Mexico on US DST just before 11.th. of March 2007. (b) Next year, a decision is made to put Mexico on the new US style DST, e.g. starting 9.th. of March 2008. Of course at the moment it looks like Mexico is in good company since Cuba, Haiti and Turks & Caicos Islands will also follow old-style US DST. But that is also a reason to keep a close eye on these countries, which might possibly change to keep it simpler to do business with the US (essentially the argument for Canada to change). I found the page http://www.cddhcu.gob.mx/bibliot/publica/inveyana/polisoc/horver/capitulo5.h tm which belongs to the Mexican Congrees (Camara de Diputados) that mentions the different timezone rules in Mexico since 1921. A fair amount of it corresponds well with the tz database (and therefore with Shanks, I presume) but there are differences. If everything is taken literally, there are at least a need to introduce new timezones for the states Campeche, Tamaulipas, Tabasco+CHS, Baja California Sur, Durango, Veracruz+Oaxaca, and Coahuila. Before I go too far with deciphering this, I would like to hear the general opinion about if this is an authoritative source or not - after all the Congress only recently got authority over timezone issues in Mexico (formally), and this list might have some goofed up details from extracting from old documents by "new" people. It does seem odd that there is no activity between 1948 and 1981. But perhaps we should just rely on Shanks for that period. Particularly I would like Paul Eggert's/David Olson's opinion on this.

Comparing updates
by Dillard, Tom Jan. 22, 2007

Jan. 22, 2007

Hi, I am hoping someone can direct me to what I hope is an easy question. I would like to compare the TZ differences between 2006m down to 2006p. What changes went in between those versions? Thanks, Tom Dillard | 972-461-4116 | tom.dillard(a)tekelec.com
