Proposed time zone package changes
by Olson, Arthur David (NIH/NCI) [E] July 17, 2006

July 17, 2006

Below are minor proposed time zone package changes; four "public domain" notices are added and the "transition time off by a second" fix circulated previously on the time zone mailing list is incorporated. --ado ------- scheck.c ------- *** /tmp/geta1403 Mon Jul 17 10:26:34 2006 --- /tmp/getb1403 Mon Jul 17 10:26:34 2006 *************** *** 1,6 **** #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)scheck.c 8.18"; #endif /* !defined lint */ #endif /* !defined NOID */ --- 1,11 ---- + /* + ** This file is in the public domain, so clarified as of + ** 2006-07-17 by Arthur David Olson. + */ + #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)scheck.c 8.19"; #endif /* !defined lint */ #endif /* !defined NOID */ ------- ialloc.c ------- *** /tmp/geta1422 Mon Jul 17 10:26:34 2006 --- /tmp/getb1422 Mon Jul 17 10:26:34 2006 *************** *** 1,6 **** #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)ialloc.c 8.29"; #endif /* !defined NOID */ #endif /* !defined lint */ --- 1,11 ---- + /* + ** This file is in the public domain, so clarified as of + ** 2006-07-17 by Arthur David Olson. + */ + #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)ialloc.c 8.30"; #endif /* !defined NOID */ #endif /* !defined lint */ ------- zic.c ------- *** /tmp/geta1441 Mon Jul 17 10:26:35 2006 --- /tmp/getb1441 Mon Jul 17 10:26:35 2006 *************** *** 1,5 **** ! static char elsieid[] = "@(#)zic.c 8.5"; #include "private.h" #include "locale.h" #include "tzfile.h" --- 1,10 ---- ! /* ! ** This file is in the public domain, so clarified as of ! ** 2006-07-17 by Arthur David Olson. ! */ + static char elsieid[] = "@(#)zic.c 8.7"; + #include "private.h" #include "locale.h" #include "tzfile.h" *************** *** 1532,1538 **** for (i = 0; i < timecnt; ++i) { j = leapcnt; while (--j >= 0) ! if (ats[i] >= trans[j]) { ats[i] = tadd(ats[i], corr[j]); break; } --- 1537,1543 ---- for (i = 0; i < timecnt; ++i) { j = leapcnt; while (--j >= 0) ! if (ats[i] > trans[j] - corr[j]) { ats[i] = tadd(ats[i], corr[j]); break; } ------- yearistype.sh ------- *** /tmp/geta1460 Mon Jul 17 10:26:35 2006 --- /tmp/getb1460 Mon Jul 17 10:26:35 2006 *************** *** 1,7 **** #! /bin/sh ! : '@(#)yearistype.sh 8.1' case $#-$1 in 2-|2-0*|2-*[!0-9]*) echo "$0: wild year - $1" >&2 --- 1,10 ---- #! /bin/sh ! : 'This file is in the public domain, so clarified as of' ! : '2006-07-17 by Arthur David Olson.' + : '@(#)yearistype.sh 8.2' + case $#-$1 in 2-|2-0*|2-*[!0-9]*) echo "$0: wild year - $1" >&2

OT: Return Receipts, was: Re: Chinese timezones 1970

Could the TZ reflector remove the header "Disposition-notification- to:"? According to http://www.rfc-editor.org/rfc/rfc2298.txt, this header requests such return receipts.

Public Domain Notices
by Mark Davis July 12, 2006

July 12, 2006

We're run into an issue on the ICU project. Some of the code files contain public domain notices, such as tzfile.h /* ** This file is in the public domain, so clarified as of ** 1996-06-05 by Arthur David Olson. */ However, other files, like zic.c are missing that notice. It is our impression that the goal was for all the code to be public domain. What we'd request is: a) an email stating that it is the intention for all the files to be public domain. b) in the next release of the code, for all the files to contain a public domain notice. (If this isn't possible, there are just 2 that we really need it to be on.) Mark

How soon is "soon"? :-) I don't have a schedule and I don't know that Arthur does either. The Moncton and Bermuda changes don't take effect until March 2007, so unless I'm missing something they're not that urgent. The proposed new Zones America/Blanc-Sablon and America/Atikokan do affect current time stamps but these are for small regions that have used standard time for decades (we think) so they normally wouldn't justify a high-priority update. I am hoping for a bit more feedback about these Canadian changes before proposing tz updates. Plus, you never know, those pesky Canadian politicians might change their minds again before next year!

tzinfo time zones/US states mapping
by Ingo Weiss July 10, 2006

July 10, 2006

Hi, I am just starting to work with tzinfo, and I need to figure out how US states map to tzinfo time zones, or in other words what time zone(s) each US state is in. If anybody has already collected this data and would be willing to share it (and thus save me a couple of hours of work) that would be highly appreciated! Ingo

Chinese timezones
by Jesper Norgaard Welen July 10, 2006

July 10, 2006

The chinese timezones don't have much description in the tz database. I am currently trying to make a map of the worlds timezones base on the Olson database, and so I miss some more information about what these timezones cover. * Asia/Harbin seems to cover the Heilongjiang region, no less no more. * Asia/Chongqing is a city lying in the Sichuan province, which is huge, so does the timezone represent all of the province? * Asia/Urumqi covers the Xinjiang province, but represents a definition problem since Kashgar also lies in the far western part of this province, so what does timezone Asia/Kashgar represent? Asia/Urumqi timezone according to the comments in the 'asia' file also covers Tibet, which lies in the Xizang province, that is huge stretching from Kashmir to Myanmar, so I don't know if all of this is covered by the Asia/Urumqi timezone alone. * Asia/Shanghai covers all the rest of China as I understand it. This is the timezone there was recently a discussion about changing to Asia/Beijing, I believe. Can anyone shed some light on this? - Jesper Nørgaard Welen

Oshu tries "DST"; S. Korea considers DST; DST in S. Korea 1949-1961?
by Paul Eggert July 10, 2006

July 10, 2006

In South Korea the Ministry of Commerce, Industry and Energy has commissioned a research project to consider the reintroduction of daylight saving time as early as 2008. See the following articles: http://e.sinchew-i.com/content.phtml?sec=2&artid=200607080000 http://www.koreaherald.co.kr/SITE/data/html_dir/2006/07/10/200607100012.asp The first story says "Korea had a daylight saving program from 1949-61, and again in 1987-88." The second story, by Annie I. Bang, gives a bit more detail: "Korea ran a daylight saving program from 1949-61 but stopped it during the 1950-53 Korean War." We have the 1987-1988 records, but for the earlier period our current database has South Korea observing DST only from May 15 through September 12, 1960. This is from Shanks & Pottenger. If anyone has more detailed info please let me know. A July 3 UPI story reports that citizens of Oshu, Japan set their clocks forward on June 21. They'll move them back August 11. This appears to be an experiment by the local chamber of commerce to get people to go to work an hour earlier, and come home an hour earlier, as part of the "Cool Biz" no-tie, no-jacket campaign that the Japanese environment ministry has been promoting lately. About 50 businesses are changing their clocks, but it does not appear to affect anyone else. Another part of the compaign sets air conditioning thermostats to 28 degrees Celsius at workplaces. Hokkaido has been doing something similar since 2004. Here are references: http://www.upi.com/NewsTrack/view.php?StoryID=20060703-070848-4585r http://www.yomiuri.co.jp/dy/national/20060703TDY09003.htm

RE: Canada timezones (2007)
by Chris Walton July 9, 2006

July 9, 2006

Patrice, If you want the short answer: we are still waiting to hear from Yukon, Nunavut, Newfoundland, and Saskatchewan. Before you write back and claim that Saskatchewan does not observe daylight time, please read the detail below. The other provinces and territories have either passed (or committed to pass) new legislation which will extend daylight time by four weeks. Version 2006d of the Olson database was updated to reflect an assumption that all provinces and territories will eventually follow the US rules by extending daylight saving. Here is the gory detail: Province of British Columbia: YES. BC will follow US rules. I don't know what the status of the legislation is at this time. The change is documented under regulation 136/2006 but I can't find this regulation on line. ### News Release: http://www2.news.gov.bc.ca/news_releases_2005-2009/2006AG0014-000330.htm Province of Alberta: YES. Alberta will follow US rules. ### Daylight Saving Amendment Act: http://www.qp.gov.ab.ca/documents/Acts/2006CH03_UNPR.cfm?frm_isbn=0779744934 City of Lloydminster: Lloydminster is a cross-border city; it straddles the Alberta-Saskatchewan border. Time on both sides of the provincial is governed by the "Lloydminster Charter". No word yet if the charter will be updated. I think we can assume that the people of Lloydminster will continue the tradition of keeping the clocks in sync with Alberta regardless of whether or not the charter is updated. ### Here are two links to the charter: Lloydminster charter (Government of Alberta web site): http://www.qp.gov.ab.ca/Documents/REGS/1979_043.CFM Lloydminster charter (Government of Saskatchewan web site): http://www.qp.gov.sk.ca/documents/english/Statutes/Historical/lloydchr.pdf Province of Saskatchewan: I am not aware of any announcements or new legislation. Most of the province does not use daylight time. The Battle Creek which includes Lloydminster does observe daylight time. The portion of the Battle Creek region that falls outside of the Lloydminster city limits and on the east side of the provincial border is covered by the Saskatchewan Time Act. I think we can assume that everybody in Battle Creek region will keep the clocks in sync with Alberta regardless or whether or not the Saskatchewan Time Act is updated. ### The Saskatchewan time act which was last updated in 1996 is about 30 pages long and rather painful to read. Here is a link to the old act: http://www.qp.gov.sk.ca/documents/English/Statutes/Statutes/T14.pdf Province of Manitoba: YES. Manitoba will follow US rules. Note: Manitoba has traditionally changed the clock every fall at 3:00 a.m. As of 2006, the transition is to take place one hour earlier at 2:00 a.m. ### The Official Time Act: http://web2.gov.mb.ca/laws/statutes/ccsm/o030e.php Province of Ontario: YES. Ontario will follow US rules. ### Ontario regulation 111/06 made under the Time Act http://www.e-laws.gov.on.ca/DBLaws/Source/Regs/English/2006/R06111_e.htm Province of Quebec: YES. Quebec will follow US rules. ### Bill 2 Legal Time Act: http://www.assnat.qc.ca/eng/37legislature2/Projets-loi/Publics/06-a002.htm Province of New Brunswick: YES. New Brunswick will follow US rules. Note: New Brunswick has traditionally changed the clocks in the spring and fall at 12:01 a.m. As of 2007, the transition is to take place 119 minutes later at 2:00 a.m. This will eliminate the excitement of having the date roll backwards. Unfortunately it means a minor update is required to the Olson database. ### An Act to Amend the Time Definition Act: http://www.gnb.ca/0062/acts/BBA-2006/Chap-19.pdf Province of Nova Scotia: YES. Nova Scotia will follow the US rules. I don't know what the status of the legislation is at this time. ### News Release: http://www.gov.ns.ca/news/details.asp?id=20060425004 Province of Prince Edward Island: YES. P.E.I. will follow US rules. The new legislation is not law yet. It passed first reading on April 20. ### Bill No. 101, An Act to Amend the Time Uniformity Act http://www.assembly.pe.ca/bills/pdf_first/62/3/bill-101.pdf Province of Newfoundland and Labrador NO commitment yet (that I know of). The change is being considered. ### There is a reference to the issue in this government news release: http://www.releases.gov.nl.ca/releases/2006/mpa/0331n01.htm Yukon Territory: I have no evidence to suggest that the government has discussed the issue. ### Here is a link to the old daylight saving portion of the interpretation act which was last updated in 1987: http://www.gov.yk.ca/legislation/regs/oic1987_056.pdf Northwest Territories: YES. N.W.T will follow US rules. ### Whoever maintains the government web site does not seem to believe in bookmarks. To see the news release, click the following link and search for "Daylight Savings Time Change" Press the "Daylight Savings Time Change" link; it will fire off a popup using JavaScript. http://www.exec.gov.nt.ca/currentnews/currentPR.asp?mode=archive Nunavut: I have no evidence to suggest that the government has formally discussed the issue. The premier made an off the wall in August of 2005 saying that he did not want to touch the issue. Regardless, I expect the people of Nunavut won't want to be out of sync with the rest of the continent and the issue will have to be addressed.
