RE: Canada 2007 (was America/Vancouver 2007)
by Chris Walton April 5, 2006

April 5, 2006

I dug up some more news releases from the Manitoba Government. It seems that the 3:00am transition from daylight savings to standard time was valid prior to 2005. Oct 1997: "This year, the official reversion to standard time occurs precisely at 3 a.m., Oct. 26, at which time clocks are turned back to 2 a.m." http://www.gov.mb.ca/chc/press/top/1997/10/1997-10-14-01.html Oct 1998: "This year, the official reversion to standard time occurs precisely at 3 a.m., Oct. 25, at which time clocks are turned back to 2 a.m. http://www.gov.mb.ca/chc/press/top/1998/10/1998-10-13-05.html Oct 1999: "This year, the official reversion to standard time occurs precisely at 3 a.m., Oct. 31, at which time clocks are turned back to 2 a.m." http://www.gov.mb.ca/chc/press/top/1999/10/1999-10-18-02.html Oct 2000: "This year, the official reversion to standard time occurs precisely at 3 a.m., Oct. 29, at which time clocks are turned back to 2 a.m." http://www.gov.mb.ca/chc/press/top/2000/10/2000-10-18-02.html Oct 2001: "This year, the official reversion to standard time occurs precisely at 3 a.m., Oct. 28, at which time clocks are turned back to 2 a.m." http://www.gov.mb.ca/chc/press/top/2001/10/2001-10-17-01.html Oct 2002: "This year, the official reversion to standard time occurs precisely at 3 a.m., Oct. 27, at which time clocks are turned back to 2 a.m." http://www.gov.mb.ca/chc/press/top/2002/10/2002-10-16-01.html Oct 2003: "This year, the official reversion to standard time occurs precisely at 3 a.m., Oct. 26, at which time clocks are turned back to 2 a.m." http://www.gov.mb.ca/chc/press/top/2003/10/2003-10-15-03.html Oct 2004: "This year, the official change back to standard time will occur at precisely 3 a.m., Sunday, Oct. 31, at which time clocks are turned back to 2 a.m." http://www.gov.mb.ca/chc/press/top/2004/10/2004-10-13-02.html Oct 2005: "This year, the precise time change occurs at 1:59 a.m. Sunday, Oct. 30 at which time clocks are set back to 1 a.m." http://www.gov.mb.ca/chc/press/top/2005/10/2005-10-17-02.html Nov 2005 # this new release is in reference to proposed legislation for 2007: "Currently, Manitobans advance their clocks forward by one hour at 2 a.m. on the first Sunday in April and turn them back at 2 a.m. the last Sunday in October." http://www.gov.mb.ca/chc/press/top/2005/11/2005-11-02-06.html I don't know if there was legislation to support the change in 2005. The new releases above are not offical statues but they do come directly from the Manitoba government so I suppose we should trust them. I think that the "Winn" rules need to be updated for 2005 and onwards. The rules should use "2:00" instead of "2:00s". Alternativily, America/Winnipeg could use the "Canada" rule from 2005 onwards. I will send e-mail to INMS asking if they are aware of the change and if they have plans to update their web site. -chris -----Original Message----- From: Chris Walton Sent: April 5, 2006 3:59 AM To: tz(a)elsie.nci.nih.gov Subject: Canada 2007 (was America/Vancouver 2007) Sorry to change the subject line mid-thread but we seem to have jumped across the country. Newfoundland has not made a decision on changes for 2007 yet. Here is the latest press release which mentions the subject: http://www.releases.gov.nl.ca/releases/2006/mpa/0331n01.htm I have not seen any announcements yet from Yukon, Northwest Territories, or Nunavut. I don't know if we should expect the same type of official statutes and timely press releases that have come from the provincial governments. However, if all three territories do decide to fall in line, NT_YK could be abandoned in favour of the "Canada" rule. BC and Alberta could use the "Canada" rule, however, I won't lose sleep if we stay with Vanc and Edm. In the end it makes no difference given that the rules are identical. I think we need to take a close look at the "Winn" rules for Manitoba. The current rule for the transition from daylight to standard time uses a time of "2:00s". If I understand the syntax correctly this is the same as "3:00" or "3:00w". The following three line note appears in the current northamerica tzdata file: "# From Paul Eggert (2000-10-02): # INMS (2000-09-12) says that, since 1988 at least, Manitoba switches from # DST at 03:00 local time. For now, assume it started in 1987." The INMS (Institute for National Measurement Standards) web site does indeed show that daylight savings in Manitoba ends at 03:00 CDT. http://inms-ienm.nrc-cnrc.gc.ca/en/faq_time_e.php#5 This "is" an official government web site but it is run by the federal government. We have to remember that in Canada, daylight savings legislation is the responsibility of the provincial and territorial governments. Here is a copy of the new official time act from the government of Manitoba web site. http://web2.gov.mb.ca/laws/statutes/ccsm/o030e.php The act indicates that daylight savings ends at 2:00am. To me, this implies 02:00 CDT and not 02:00 CST. Would a lawyer interpret it differently? I could not find a copy of the old act, so I don't know what it used to say. I did find a news release from the Alberta government dated Oct 17/2005 which states: "This year, the precise time change occurs at 1:59 a.m. Sunday, Oct. 30 at which time clocks are set back to 1 a.m." http://www.gov.mb.ca/chc/press/top/2005/10/2005-10-17-02.html The news release is not an official document but I beginning to wonder if the 03:00 is just a typo on the INMS web site. Is there anybody from Manitoba on this mailing list? Is there any information other than the INMS web site that indicates Manitoba ever switched the clock at 3:00am? -chris -----Original Message----- From: Paul Eggert [mailto:eggert@CS.UCLA.EDU] Sent: Tue 4/4/2006 8:54 PM To: tz(a)elsie.nci.nih.gov Cc: Chris Walton Subject: Re: America/Vancouver 2007 "Chris Walton" <Chris.Walton(a)telus.com> writes: > http://www2.news.gov.bc.ca/news_releases_2005-2009/2006AG0014-000330.h > tm Thanks for the heads-up.

Could be, since people are falling into line so quickly. I guess we should do the same for Winn and Edm rules as well? And NT_YK? What about Newfoundland?

America/Vancouver 2007
by Chris Walton April 5, 2006

April 5, 2006

The British Columbia government announced yesterday that it will adjust daylight savings next year to align with changes in the U.S. and the rest of Canada. The change will take effect on March 11/2007 (Same as U.S. and rest of Canada). Two zones are impacted: America/Vancouver America/Dawson_Creek I think it makes sense to start using the existing "Canada" rules which have already been updated instead of creating more "Vanc" rules. Here is a reference: http://www2.news.gov.bc.ca/news_releases_2005-2009/2006AG0014-000330.htm If possible, can the appropriate changes be squeezed into 2006c? Thanks -chris

Haiti on DST
by Steffen Thorsen April 4, 2006

April 4, 2006

I have been informed by users that Haiti observes DST this year like last year, so the current "only" rule for 2005 might be changed to a "max" rule or to last until 2006. (Who knows if they will observe DST next year or if they will extend their DST like US/Canada next year). I have found this article about it (in French): http://www.haitipressnetwork.com/news.cfm?articleID=7612 The reason seems to be an energy crisis. Best regards, Steffen

British Columbia to move to US rules next year; Bermuda likely too
by Paul Eggert April 4, 2006

April 4, 2006

The Canadian Press reports that British Columbia will follow the new US daylight saving rules next year; see <http://www.theglobeandmail.com/servlet/story/RTGAM.20060401.wbc0401/BNStory…> (2006-04-01). This isn't urgent, so I'll include the appropriate change in my next proposed patch. This will still leave Newfoundland, Northwest Territories, and Yukon as the "holdouts" in Canada as far as the tz database is concerned; most likely they will switch to the new US rules, but we don't have word on this yet so for now they are listed as sticking to the old rules. Sam Strangeways reports in the Royal Gazette that a confidential report is being delivered to the Cabinet of Bermuda this month as to whether Bermuda should switch from the old to the new US rules. My reading between the lines is that they'll switch. See <http://www.theroyalgazette.com/apps/pbcs.dll/article?AID=/20060329/NEWS/103…> (2006-03-29). But we can wait for more info on this. Also, the old US rules are still listed for Mexico, the Bahamas, Cuba, and Turks and Caicos, even though most likely some (perhaps all) these regious will switch to the new US rules before 2007.

Tzcode2006c.tar.gz and tzdata2006c.tar.gz
by Olson, Arthur David (NIH/NCI) [E] April 3, 2006

The files... ftp://elsie.nci.nih.gov/pub/tzcode2006c.tar.gz ...and... ftp://elsie.nci.nih.gov/pub/tzdata2006c.tar.gz ...are now available. These reflect the two sets of data changes circulated late last month on the time zone mailing list by Paul Eggert; they also reflect a fencepost error fix in zic.c and changes to zic.c and the "europe" file to minimize differences between output produced by the old 32-bit zic and the new 64-bit version. The old 32-bit code remains available as ftp://elsie.nci.nih.gov/pub/old-tzcode-32-bit-output.tar.gz --ado

unchanged binary output
by Arthur David Olson April 1, 2006

April 1, 2006

Below are changes to "zic.c" and "europe" that should arrange for all but one of the 64-bit zic output files to have first parts that are bit-for-bit identical (except for TZif/TZif2 differences) to files produced by the old 32-bit compiler. The only exception is America/Juneau; the 64-bit compiler notices that Yukon Daylight Time (YDT) was never actually used in Juneau and optimizes out some information. The files should, however, be identical from a functional standpoint. --ado ------- zic.c ------- *** /tmp/geta5518 Sat Apr 1 14:29:54 2006 --- /tmp/getb5518 Sat Apr 1 14:29:54 2006 *************** *** 1,4 **** ! static char elsieid[] = "@(#)zic.c 8.3"; #include "private.h" #include "locale.h" --- 1,4 ---- ! static char elsieid[] = "@(#)zic.c 8.4"; #include "private.h" #include "locale.h" *************** *** 1630,1643 **** indmap[i] = -1; thischarcnt = 0; for (i = 0; i < typecnt; ++i) { if (!writetype[i]) continue; if (indmap[abbrinds[i]] >= 0) continue; ! indmap[abbrinds[i]] = thischarcnt; !

Of course if they are split up, remember that it seems to be the first act of any new government to change the daylight saving time rules. In which case, we'll have an entry for each of the new entities anyway.
