Hi, The latest version of the timezone data file ftp://elsie.nci.nih.gov/pub/tzdata2006c.tar.gz contains the updated time offset for Sri Lanka, but the text field is set to IST. I think this needs to be corrected to LKT. # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Colombo 5:19:24 - LMT 1880 5:19:32 - MMT 1906 # Moratuwa Mean Time 5:30 - IST 1942 Jan 5 5:30 0:30 IHST 1942 Sep 5:30 1:00 IST 1945 Oct 16 2:00 5:30 - IST 1996 May 25 0:00 6:30 - LKT 1996 Oct 26 0:30 6:00 - LKT 2006 Apr 14 5:30 - IST Thanks.

RE: proposed tz changes for Haiti, Sri Lanka, and Canada

Paul, The patch looks accurate with the exception of the two Yukon zones. America/Whitehorse is now showing up with M%T instead of P%T. America/Dawson shows up with an offset of -9:00 hours instead of -8:00 hours. I suspect that these are both typos. -chris * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * --- northamerica.p 2006-04-14 10:38:44.182628000 -0400 +++ northamerica 2006-04-14 10:43:01.413523000 -0400 @@ -1640,11 +1640,11 @@ Zone America/Inuvik -8:54:00 - LMT 1884 Zone America/Whitehorse -9:00:12 - LMT 1900 Aug 20 -9:00 NT_YK Y%sT 1966 Jul 1 2:00 -8:00 NT_YK P%sT 1980 - -8:00 Canada M%sT + -8:00 Canada P%sT Zone America/Dawson -9:17:40 - LMT 1900 Aug 20 -9:00 NT_YK Y%sT 1973 Oct 28 0:00 -8:00 NT_YK P%sT 1980 - -9:00 Canada P%sT + -8:00 Canada P%sT ############################################################################### -----Original Message----- From: Paul Eggert [mailto:eggert@CS.UCLA.EDU] Sent: April 14, 2006 6:28 AM To: tz(a)lecserver.nci.nih.gov Subject: proposed tz changes for Haiti, Sri Lanka, and Canada Here are proposed changes to the tz database that I hope finishes off the usual March madness of DST rule changes. As I write, the tz database is incorrect for current time stamps in Haiti (for some months) and for Sri Lanka (for the next 8 hours or so) so it's time to get these changes out the door. * Haiti observes DST this year, and probably in the future. (Thanks to Steffen Thorsen for this info.) * The Sri Lanka time zone change from +06:00 to +05:30 occurs at April 15 00:30 local time, not at April 14 00:00. (Thanks to Jesper Norgaard Welen for this info.) * It seems it's safer to predict that all of Canada will adopt US DST rules next year, than to predict, as we did, that there will be some holdouts. (Thanks to Chris Walton for this info.) * From 1967 through 1986, Manitoba's fall transitions were at 03:00 local time, not 02:00.

Sri Lanka GMT offset adjustment
by Jesper Norgaard Welen April 14, 2006

April 14, 2006

I have found a website that claims a different time for the GMT offset change for Sri Lanka than we have in the present 2006c. The page http://news.sinhalaya.com/wmview.php?ArtID=11002 claims the following: 13 April 2006 - 07:38 Change in Sri Lanka Standard Time Ministers have approved a Cabinet Memorandum submitted by Disaster Management and Human Rights Minister Mahinda Samarasinghe to revert the clock by 30 minutes from April 14 midnight. With the implementation of this decision, the Sri Lanka Standard Time (SLST) reverts back to the zone GMT +5 1/2 hours, which was used prior to May 24, 1996 for over 50 years. It is necessary to put the clock back by half an hour at 0030 hrs on April 15. This means 0030 hrs on April 15, 2006 (midnight of April 14, 2006 +30 minutes) at present, become 2400 hours of April 14, 2006 (midnight of April 14, 2006). === end of article === This is different than the tz database which will have the change at midnight of the 13.th. of April, thus putting time back to 23:30 the 13.th. of April. Steffen Thorsen on http://www.timeanddate.com/worldclock/results.html?query=colombo however has it from 13.th. of April at 0:30 returning to 13.th. of April 0:00, e.g. almost 48 hours before news.sinhalay.com will have it. Perhaps Steffen could enlighten us on his source (usually local web users)? Although the article from news.sinhalay.com is not official, it is the first one I have seen that gives explicit instructions about what time to adjust the clocks. So who are we to believe?

America/Winnipeg 2:00am or 3:00am (was Canada 2007)
by Chris Walton April 13, 2006

April 13, 2006

Sorry to change the subject of the e-mail thread again. Paul E. and I received some information from the folks at the National Research Council (NRC) in Ottawa regarding the Manitoba Official Time Act. This is what we learned: March 22/1967 - Official Time Act for Manitoba received assent. I have not personally seen a copy of this act but my understanding (based on e-mail from Rob Douglas at the NRC) is that section 2 reads: "2 Throughout the province the official time which shall be used and observed shall be (a) except between two o'clock Central Standard Time in the morning of the last Sunday in April of each year and two o'clock Central Standard Time in the morning of the last Sunday in October next following, Central Standard Time; and (b) between two o'clock Central Standard Time in the morning of the last Sunday in April of each year and two o'clock Central Standard Time in the morning of the last Sunday in October next following, one hour in advance of Central Standard Time." The wording explicitly indicates that the transition from daylight time to standard time should take place at 02:00 CST. 02:00 CST is equivalent to 03:00 CDT or 3:00 a.m. wall time. A rather interesting bit of information which Rob noticed: the French version of Act was worded differently than the English version. My French is poor, but here is a rough English translation of the French version of the Act: "the first Sunday of April at two in the morning and the last Sunday of October at the same time". This would seem to imply daylight saving time ended at 02:00 CDT instead of 02:00 CST! Apparently if there are differences in translation, the English version takes priority. The English version of the Act does "not" reflect the current "end time" specified in the TZDATA rules from 1967 to 1986. TZDATA needs to be updated accordingly. March 27/1987 - assent of an amendment to the Official Time Act. http://www.canlii.org/mb/laws/sta/o-30/20050510/whole.html # English http://www.canlii.org/mb/legis/loi/o-30/20050510/tout.html # French The only change in both the French and English versions of the amendment was the starting date (first Sunday in April instead of last Sunday of April). The updated act reads: "2 Throughout the province the official time which shall be used and observed shall be (a) except between two o'clock Central Standard Time in the morning of the first Sunday in April of each year and two o'clock Central Standard Time in the morning of the last Sunday in October next following, Central Standard Time; and (b) between two o'clock Central Standard Time in the morning of the first Sunday in April of each year and two o'clock Central Standard Time in the morning of the last Sunday in October next following, one hour in advance of Central Standard Time." The English version of this amendment "does" match Current TZDATA rules from 1987 onwards. Dec 08/2005: - assent of another amendment to the Official Time Act: http://web2.gov.mb.ca/laws/statutes/ccsm/o030e.php # English http://web2.gov.mb.ca/laws/statutes/ccsm/o030e.php # French The new wording is significantly different than the wording in the original act. The French and English versions are finally in sync. The amended act reads: "2(2)Subject to subsection (3), daylight saving time being the time one hour in advance of Central Standard Time must be used and observed throughout the province (a) in 2006, from 2:00 a.m. on the first Sunday in April until 2:00 a.m. on the last Sunday in October; and (b) in 2007 and every year after that, from 2:00 a.m. on the second Sunday in March until 2:00 a.m. on the first Sunday in November. The new wording does not specify "Standard Time" or "Daylight Saving Time". I interpreted this to mean that daylight savings ends at 02:00 CDT. Rob Douglas of the NRC agrees with this interpretation. There is apparently some rational to this interpretation; the time of 2:00 a.m. must be treated as 02:00 "Official Time". Official Time is defined in section 1 of the act. Up until the point in time that the clocks move back, "Official Time" is "Daylight Saving Time" so 2:00 a.m. is 2:00 CDT. The NRC-INMS web page has been updated to reflect that daylight saving time in Manitoba now ends at 02:00 CDT. http://inms-ienm.nrc-cnrc.gc.ca/en/faq_time_e.php#5 There is a note that says the start times have been in effect since 1988. There is currently no note about end times; we may see a further update and/or a footnote in the near future. Based on the information in the original Time Act and the two amendments, the transitions from daylight time to standard time specified in TZDATA need to be updated as follows: 1916-1966 No change to exiting rules. 1967-2005: 03:00 CDT 2006-END_OF_TIME: 02:00 CDT Paul E. has suggested that the transition from daylight time to standard time in 1966 should be changed from 02:00 CDT to 03:00 CDT. i.e. we should treat 1966 like 1967. My opinion is that we should leave 1966 alone. There was no legislation (that I know of) in 1966 and the rest of the Country (with some exceptions) had traditionally used 2:00 wall time for the switch. I will leave this up to Paul to make a final decision on what he wants to do with 1966. And one last note... Two of the Manitoba government news releases which I referenced in my previous e-mail should be ignored; there is no legislation to back them up. NRC is ignoring them so we should too! Both news releases lead one to believe that daylight saving time in 2005 (and prior years) ended at 02:00 CDT instead of 02:00 CST. For reference, here are the URLs. http://www.gov.mb.ca/chc/press/top/2005/10/2005-10-17-02.html http://www.gov.mb.ca/chc/press/top/2005/11/2005-11-02-06.html We need to keep an eye on the Manitoba government next October and make sure that they don't publish more incorrect information. -chris -----Original Message----- From: Chris Walton Sent: April 5, 2006 12:05 PM To: 'tz(a)elsie.nci.nih.gov' Subject: RE: Canada 2007 (was America/Vancouver 2007) I dug up some more news releases from the Manitoba Government.

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.

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.

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. "At the back of the Daylight Saving scheme I detect the bony, blue-fingered hand of Puritanism, eager to push people into bed earlier, and get them up earlier, to make them healthy, wealthy and wise in spite of themselves." - Robertson Davies -- 73 de ke9tv/2, Kevin KENNY GE Corporate Research & Development kennykb(a)crd.ge.com P.

Re: tz behavior difference TZif vs. TZif2
by Robbin Kawabata March 30, 2006

March 30, 2006

After building zic.c with the changes of 3/25/06 (which fixed a fencepost error), and comparing the TZif zoneinfo binaries with the TZif2 binaries, most timezones were identical (modulo the "TZif" vs. "TZif2" strings). However, seven timezones below had other differences: ./Africa/Windhoek ./Europe/London (links ./Europe/Belfast, ./GB, ./GB-Eire) ./Europe/Gibraltar ./Europe/Rome (links ./Europe/Vatican, ./Europe/San_Marino) ./Europe/Malta ./Europe/Madrid ./America/Juneau Should the TZif vs. TZif2 binaries compare exactly except for the '2' in "TZif2"?

Re: Handling %s format strings

eggert(a)cs.ucla.edu said: > Which implementation is this? Is this a parser of tz data that is > written in Tcl, or is written in some other language and is commonly > available in Tcl? If so, I'd like to mention it in tz-link.htm As of Tcl 8.5 (now in alpha release), Tcl includes in its distribution a set of files that are an ASCII version of tzdata, and Tcl/C code to parse and format date/time strings using these as the time zone reference. There is a parser for the tz data written in Tcl supplied as part of this distribution in the 'tools' directory; the parser is intended primarily for use by developers of the Tcl system itself but can obviously be used by system administrators and others who wish to keep their tz data up to date between installing Tcl releases. Tcl is also capable of reading the binary zoneinfo files (and does so if its own tz data is not installed). The Tcl Improvement Proposal that put this material into the Tcl core can be found at http://tip.tcl.tk/173.html, and the manual page for the revised 'clock' command is at http://www.tcl.tk/man/tcl8.5/TclCmd/clock.htm The current alpha release of Tcl 8.5 is at http://www.tcl.tk/software/tcltk/8.5.html If you want to review the code of Tcl's 'zic' file parser, the CVS HEAD of the source file is at http://cvs.sourceforge.net/viewcvs.py/*checkout*/tcl/tcl/tools/tclZIC.tcl?c… 8.5a4 should be out Real Soon Now (the release manager keeps bugging me about bugs, and I'm going to finish this message and go off to fix some non-clock-related ones). -- 73 de ke9tv/2, Kevin KENNY GE Corporate Research & Development kennykb(a)crd.ge.com P.

I seem to recall that the 'zic' man page had something about this. Either that or I took the Star Wars approach, "use the source, Luke!" -- 73 de ke9tv/2, Kevin KENNY GE Corporate Research & Development kennykb(a)crd.ge.com P. O. Box 8, Bldg.

Handling %s format strings
by Philip Ross March 27, 2006

March 27, 2006

I'm the developer of TZInfo (http://tzinfo.rubyforge.org/) a Ruby library that uses the tz database (thanks for the link on twinsun.com by the way). I'm running into an issue where I'm unable to determine what the zone name is in cases where %s is used as the entire format string. This happens in the following zones: Africa/Accra Africa/Freetown Europe/Amsterdam Europe/Gibraltar Europe/London Europe/Moscow Take Africa/Accra as an example. Starting from 1918, this zone uses the Ghana rules with a %s format string. The Ghana rules only start to be defined from 1936. Europe/London contains two examples of the problem. The first happens similarly to Africa/Accra. LMT ends in 1847. The next period has a format of %s, but the first rule in GB-Eire doesn't start until 1916. The second example is with the period starting in 1971. Again this has a format of %s but a first rule starting in 1972. Basically, my problem is in dealing with the gap until the first rule/transition within a period of the zones. How should I be interpreting the data in these cases? Thanks, Philip Ross

more proposed UK legislation to change the clocks
by Peter Ilieve March 27, 2006

March 27, 2006

There as a comment piece in the Independent (a UK newspaper) today that said that Lord Tanlaw has proposed changing the UK's timezone. The Independent only makes such stuff available on-line for a fee, but you can see the start of the piece at <http://comment.independent.co.uk/commentators/ article353873.ece>. The Cambridge mathematician mentioned is presumably Joseph Myers. I've looked on the UK Parliament website and it seems Lord Tanlaw introduced his Lighter Evenings (Experiment) Bill on 30 November last year. The Bill itself and the noble Lord's explanatory notes can be found linked from <http://www.publications.parliament.uk/pa/ld200506/ldbills/ 048/2006048.htm>. The initial debate, such as it was, occupies four lines of Hansard at <http://www.publications.parliament.uk/pa/ld199900/ldhansrd/pdvn/ lds05/text/51130-04.htm#topichd_4>. (To be fair, the first reading of a Bill is usually like this, just a formality.) It came up for second reading on 24 March, and the much more substantial debate can be found at <http://www.publications.parliament.uk/pa/ld199900/ldhansrd/pdvn/ lds06/text/60324-01.htm#60324-01_head0>. It was approved and will now go to a committee of the whole house for its committee stage. If it gets past that it will go to the Commons. The Bill proposes to move England's time one hour ahead in winter and summer for an experimental period starting in October this year and ending in October 2009. Scotland would be allowed to opt in to this experiment by an amendment to the Scotland Act (timezone matters are currently reserved to Westminster so Scotland can't do it's own thing without such an amendment). Wales and Northern Ireland would similarly be allowed to opt in. Lord Tanlaw has in the past tried and failed to change the legal definition of the UK's standard time from GMT to UTC. Personally I don't think he will be any more successful this time. At the Bill's current rate of progress it's very hard to see any experiment starting this year even if the principle is accepted.
