proposed tz changes for Paraguay, Brazil, Wayne County, etc.
by Paul Eggert Oct. 5, 2000

Oct. 5, 2000

Here are all the patches for the tz data that I've been accumulating since August. The most pressing changes are those for Brazil, Paraguay, and Wayne County, Kentucky. I haven't had time to incorporate all the changes that I'd like for historical timestamps, or for some new Zones for slightly different rules in Canada (notably for New Brunswick), but we need a new version right away for Paraguay at least. Changes affecting present or future time stamps: * Paraguay started observing DST on 10-01. (Thanks to Steffen Thorsen for this info.) * Brazil observes DST from 10-29 to 02-18 this summer. (Thanks to everyone who reported this.) * Add a Zone America/Kentucky/Monticello for Wayne County, KY, which is switching to Eastern Time on 10-29. (Thanks to Rich Wales and Rives McDow for this info.) * Add a link America/Kentucky/Louisville -> America/Louisville, for symmetry with Monticello. * Lord Howe changes its clocks at the same absolute time as NSW. (Thanks to James Lonergan via Jesper Norgaard for this info.) * Newfoundland switches to and from DST at 00:01 local time, not 02:00. Manitoba switches from DST at 03:00 local time, not 02:00. Source: <http://www.nrc.ca/inms/time/tze.html> * The following Zone names have been changed to reflect typical English usage these days. The old names are in the `backward' file and so will continue to work in the typical case where you have backward-compatibility enabled. Asia/Thimbu -> Asia/Thimphu Asia/Ashkhabad -> Asia/Ashgabat (Thanks to Oscar van Vlijmen for this info.) Changes affecting past time stamps only * Abbreviations for US daylight saving times between 1945-08-14 23:00 UTC and 1945-09-30 02:00 LT are now suffixed "PT" for "Peace Time", not "WT" for "War Time". This matches historical practice in US radio broadcasts. We don't know about about 1919's "War Time", so we'll leave it alone for now. (Thanks to Arthur David Olson for this info.) Changes affecting commentary only * Add a rule in `Theory' advising not to change established names if they only marginally violate the other rules, and to put old names in `backward'. * Update several links in tz-link.htm, notably: - The Burbs converter is renamed to tick2tock.com. - Distinguish between the Time Service and the Astronomical Applications departments of the USNO. - iata.org -> www.iata.org - The CIA renamed (and presumably updated) its time zone map. - Add a link to www.worldtimeserver.com. - Give a link to the full text of McCarthy and Klepczynski's proposal to remove leap seconds. This proposal is now being considered by the IAU. * Bahrain: Al-Manamah -> Al Manamah * China: Added the following alternate spellings, mostly pinyin: Haerbin, Chongqing, Urumchi, Kashi, Kaxgar, Xianggang, Macau, Aomen * Cyprus: Nicosia is now listed under Europe as well as under Asia. * Greenland: Ittoqqortoormiit was misspelled. Clarify that Thule is the base. * Iraq: Fixed a typo that caused the initials to be "ADT" all year long. * Kyrgyzstan: Name of country changed from "Kirgizstan". * Laos: Added Viangchan as an alternate spelling for Vientiane. * Qatar: Added Doha as an alternate spelling for Al Dawhah. * Syria: Added Dimashq as an alternate spelling for Damascus. * US: Add comments roughly identifying the extent of each Zone. Rives McDow reports that the following changes have occurred in the US since 1985. I haven't had time to create proper Zone entries for them yet, but I added his comments. - Kearny County, KS (put all of county on central; previously split between MST and CST) ... 1990-10 - Oliver County, ND (from MST to CST) ... 1992-10 - West Wendover, NV (from PST TO MST) ... 1999-10 - There is another change in the offing; Mercer County, ND is looking to change from MT to CT. It is possible that two other ND counties (Sioux and Morton) will look to change also. If made, the earliest a change would be effective is October 2001. * Canada: Mention H. David Matthews and Mary Vincent's nice article <http://www.canadiangeographic.ca/SO98/geomap.htm> about actual vs legal time zones in Canada. Mention INMS, which attempts to document current practice in Canada, inspired (I think) by Matthews and Vincent's article. Mention INMS's claim that New Brunswick switches at 00:01, not 02:00. (We need a new Zone for this, but I haven't had time yet to verify it.) Clarify that the America/St_Johns Zone includes southeast Labrador, including Port Hope Simpson and Mary's Harbour, but excluding Black Tickle. Matthews and Vincent verified that Atikokan observes CST all year, and say also that Pickle Lake and New Osnaburgh are the same. They also say that far east Quebec observes AST. (We may need new Zones for these cases.) They also write that Big Trout Lake observes CST/CDT, and that Upsala and Shebandowan observe EST/EDT, all in violation of the official Ontario rules; and that the rules are also not observed by other far east Quebecois, by Denare Beach and Creighton, Saskatchewan, and by Creston, BC. Include commentary about this too, as well as their (now-dated) commentary about Alert and Eureka, Nunavut and other far-flung places in the north. (Thanks to Rob Douglas of the INMS for the pointer to Matthews and Vincent.) * Australia: Twin Towns Services Club (in Tweed Heads, near the Queensland border) will maintain Queensland time. (Thanks to Eric Ulevik for this.) * UK: The BBC used `DBST', not `BDST', during the war. (Thanks to Joseph S. Meyers for this.) =================================================================== RCS file: RCS/asia,v retrieving revision 2000.5 retrieving revision 2000.5.0.1 diff -pu -r2000.5 -r2000.5.0.1 --- asia 2000/07/31 13:26:42 2000.5 +++ asia 2000/10/03 06:01:09 2000.5.0.1 @@ -110,7 +110,7 @@ Zone Asia/Baku 3:19:24 - LMT 1924 May 2 # Bahrain # Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone Asia/Bahrain 3:22:20 - LMT 1920 # Al-Manamah +Zone Asia/Bahrain 3:22:20 - LMT 1920 # Al Manamah 4:00 - GST 1972 Jun 3:00 - AST @@ -126,7 +126,7 @@ Zone Asia/Dacca 6:01:40 - LMT 1890 # Bhutan # Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone Asia/Thimbu 5:58:36 - LMT 1947 Aug 15 +Zone Asia/Thimphu 5:58:36 - LMT 1947 Aug 15 # or Thimbu 5:30 - IST 1987 Oct 6:00 - BTT # Bhutan Time @@ -196,7 +196,7 @@ Rule PRC 1986 only - May 4 0:00 1:00 D Rule PRC 1986 1991 - Sep Sun>=11 0:00 0 S Rule PRC 1987 1991 - Apr Sun>=10 0:00 1:00 D # Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone Asia/Harbin 8:26:44 - LMT 1928 +Zone Asia/Harbin 8:26:44 - LMT 1928 # or Haerbin 8:30 - HART 1932 Mar # Harbin Time 8:00 - CST 1940 9:00 - HART 1966 May @@ -205,17 +205,17 @@ Zone Asia/Harbin 8:26:44 - LMT 1928 Zone Asia/Shanghai 8:05:52 - LMT 1928 8:00 Shang C%sT 1949 8:00 PRC C%sT -Zone Asia/Chungking 7:06:20 - LMT 1928 +Zone Asia/Chungking 7:06:20 - LMT 1928 # or Chongqing 7:00 - CHUT 1980 May # Chungking Time 8:00 PRC C%sT -Zone Asia/Urumqi 5:50:20 - LMT 1928 +Zone Asia/Urumqi 5:50:20 - LMT 1928 # or Urumchi 6:00 - URUT 1980 May # Urumqi Time 8:00 PRC C%sT -Zone Asia/Kashgar 5:03:56 - LMT 1928 +Zone Asia/Kashgar 5:03:56 - LMT 1928 # or Kashi or Kaxgar 5:30 - KAST 1940 # Kashgar Time 5:00 - KAST 1980 May 8:00 PRC C%sT -# Hong Kong +# Hong Kong (Xianggang) # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule HK 1946 only - Apr 20 3:30 1:00 S Rule HK 1946 only - Dec 1 3:30 0 - @@ -261,7 +261,7 @@ Rule Taiwan 1980 only - Sep 30 0:00 0 S Zone Asia/Taipei 8:06:00 - LMT 1896 8:00 Taiwan C%sT -# Macao +# Macao (Macau, Aomen) # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Macao 1961 1962 - Mar Sun>=16 3:30 1:00 S Rule Macao 1961 1964 - Nov Sun>=1 3:30 0 - @@ -302,6 +302,10 @@ Zone Asia/Nicosia 2:13:28 - LMT 1921 Nov 2:00 EUAsia EE%sT # IATA SSIM (1998-09) has Cyprus using EU rules for the first time. +# Classically, Cyprus belongs to Asia; e.g. see Herodotus, Histories, I.72. +# However, for various reasons many users expect to find it under Europe. +Link Asia/Nicosia Europe/Nicosia + # Georgia # From Paul Eggert <eggert(a)twinsun.com> (1994-11-19): # Today's _Economist_ (p 60) reports that Georgia moved its clocks forward @@ -483,7 +487,7 @@ Rule Iraq 1986 1990 - Mar lastSun 1:00s # IATA SSIM (1991/1996) says Apr 1 12:01am UTC; guess the `:01' is a typo. # Shanks says Iraq did not observe DST 1992/1997 or 1999 on; ignore this.

TimeZone Information
by Burtenshaw, Craig Oct. 4, 2000

Oct. 4, 2000

Hi, Recently I received a new TimeZone file for Australia and it's 2000 timezone changes. I unzipped the file and replaced the current australasia file with the one in the tz2000f.tar.gz file I was sent. However, the machine has not converted to Daylight Savings time yet. Even after rebooting the machine. Could you give me an idea on how to change the date of the machine to reflect daylight savings ? I did alter it manually 'date MMDDHHMIYYYY' and this worked for a little while, but when I rebooted the machine it reverted back to Non Daylight savings time. Thankyou in advance.

The Greek week names Monday through Thursday (Deftera, Triti, Tetarti, Pempti - with apologies for maybe non-standard transliteration) contain the plain words 2nd, 3rd, 4th, and 5th, respectively.

Zeller, Kalender-Formeln, Acta Mathematica, Vol. 9, Nov. 1886 I haven't read the original article (I don't read German), but I have seen a translation whose location escapes me now. I think if you translate his original formulas unchanged into C, and assume nonnegative years, they would look like this: /* Calculcate weekday number for Gregorian date YYYY-MM-DD. */ int jan_or_feb = MM <= 2; int y = YYYY - jan_or_feb; int J = y / 100; // century number int K = y % 100; // year number within the same int m = MM + 12 * jan_or_feb; // month number int q = DD; // day number in the month int h = (q + ((m + 1) * 26) / 10 + K + K/4 + J/4 - 2*J) % 7; // weekday number (1 is Sunday) However, this ignores overflows and doesn't handle negative years correctly. If you want it to work more generally, you need to alter the formulas, e.g. to something like the following. Please note that I've written this code by hand just now without testing it, so it's quite possibly buggy. #define DIV(a, b) (((a)/(b)) - ((a)%(b) < 0)) int jan_or_feb = MM <= 2; int K1 = YYYY % 100; int K2 = K1 - (K1 == 0 & jan_or_feb); int J = YYYY / 100 - (K2 < 0); int K = (K2 + 100) % 100; int m = MM + 12 * jan_or_feb; int q = DD; int h1 = (q + ((m + 1) * 26) / 10 + K + DIV(K,4) + DIV(J,4) - 2*J) % 7; int h = (h1 + 6) % 7;

Alternative place names?

One of the TZ prescriptions is: "Use the most populous among locations in a country's time zone, e.g. prefer `Shanghai' to `Beijing'. Among locations with similar populations, pick the best-known location, e.g. prefer `Rome' to `Milan'." The rationale of the 11 Theory prescriptions is of course: The user has to be able to find the wanted timezone immediately. I am NOT proposing to change the Theory rules, but I wonder: population count, popularity, media exposure all change, a capital hardly or not. A capital is or should be known to everybody. Haven't we all had some kind of geography lessons, years or decades ago? If in a TZ application the end user is able to see the commented alternative names, then in some cases alternatives should be mentioned in the data files. If not, mentioning alternatives still could be useful to the developers of Windows, Macintosh and web derivatives of the TZ application. > Paul Eggert, Vadim Vygonets, Antoine Leca / China: Chongqing A recurring problem is that people inside and outside of China don't like the official pinyin transliteration. Most professional map makers however use pinyin. Officially (Peking University course) the q- sound is an aspirated voiceless affricate, with j- the unaspirated voiceless counterpart. In practice j- sounds more like the (voiced!) g- in English genuine and q- more like the ch- in English chew. How Chongqing is pronounced in Chongqing I do not know. What I do know is that Chongqing is the official pinyin transliteration. Chung is a British transliteration (Wade, 1867), indeed: tch'ong is the French EFEO (1902) transliteration, but k'ing is the French transliteration for pinyin qing, whereas ch'ing would be the British transliteration. I'll vote for pinyin Chongqing. > Antoine Leca / Cambodia: Phnum Penh There is a (Unicode) "Proposal for encoding the Khmer script", by Maurice Bauhahn, a proposal to ISO-IEC JTC1/SC2/WG2.

Dunno, the book "The world almanac and book of facts", World Almanac Books, 1998, gives on page 542 a list of US state capitals with Sacramento as the only capital of California, Springfield (not Chicago) as capital of Illinois, etcetera. Good maps will also show the one and only capital of states. For US states with 2 or more timezones, one could use the most populous county seats or courthouses. For instance, Indiana has 92 counties to choose from (ibid, page 424). The same information can be found (elsewhere) for Canada. But I think it's a bit futile to rework the whole tz database only for the sake of being administratively correct. Here and there a couple of obvious corrections won't hurt.

Actually, capitals change suprisingly often. E.g. Kazakhstan changed its capital in 1997, and then changed the capital's name in 1998. (Good thing they didn't use new time zone rules too, or we'd have had to track that mess.) Even China, the most populous country in the world, changed its capital twice in the last century (in 1928 and again in 1949) and there was a period in which the location of its capital was in serious dispute. Capitals are political creatures, and we are trying to avoid politics here as much as possible, so I don't want to give the "capitalness" of a city much weight. > Chung is a British transliteration (Wade, 1867), indeed: tch'ong is the > French EFEO (1902) transliteration, but k'ing is the French transliteration > for pinyin qing, whereas ch'ing would be the British transliteration. The name "Chungking" is not a systematic transliteration; it is merely traditional. It's probably the weakest of the existing Chinese names, i.e. the one where there is the strongest reason to change, as I get the feeling that the Pinyin transliteration "Chongqing" is gaining wide popularity in ordinary English usage. Google reports 38k English-language hits for "Chongqing" and 21k for "Chungking", so if we were choosing now "Chongqing" might well be the winner. But I'm not sure that this is enough to change an established name.

One observation to add is about numbering/enumerating/counting in general: 1st, 2nd, 3rd, ... well - I've never heard about "the 0-st". Enumerating starting with zero seems to have come in vogue with C, due to the simpler address calculation (saves some micro seconds?).

Hi, I was informed this was the right place to inform this. If you are not, I both apologize and ask if you can direct this to the right person. I would like to report that the Light Time Saving estimates for Brazil are incorrect. The new correct time savings for this year are - begin 08 Oct 2000 00:00:00 - end 18 Feb 2001 00:00:00 Unfortunaly, it is not clear if the 2nd weekend of September will be the official beginning for consequent years. The same applies for the end date. Therefore, I would advise maintaining the actual policy, yet adding this year's information.

Forgot to mention something. You talk about "formal capital", but that can only be the case if it is written down somewhere in the legislation, but there is nothing about that anywhere. My (Dutch) encyclopedia (which postdates my schooldays by quite some years) says: "Generally Amsterdam is seen as the capital of the Netherlands although the seat of government is in The Hague."

What I was trying to say (perhaps infelicitously) is that the geographic dividing line is fuzzy in places (e.g. are the Mugadzhar mountains in Europe or in Asia?) but Cyprus is pretty clearly on the Asian side. Here's a quote that states things fairly accurately, I think: Geographically, Cyprus is considered to be a part of West Asia (this Mediterranean island is much closer to the mainland of Asia than to that of Europe). However, due to cultural, demographic, and historical reasons, it is often considered as a part of Europe. http://www.ozemail.com.au/~natinfo/asia3-2.htm#cyprus However, after some more research I agree that the point is disputable. In particular, the Encyclopedia Britannica flatly says that Cyprus is part of Europe. See <http://www.britannica.com/seo/e/europe/>. > The problem with Cyprus is that, at least as he said, Yiango was > unable to find Cyprus TZ because it cannot found it under > Europe/Nicosia. Yes, that's perhaps the best practical argument for putting it under Europe. I guess you have talked me into adding something like this: # Classically, Cyprus belongs to Asia; e.g. see Herodotus, Histories, I.72. # However, for various reasons many users expect to find it under Europe.
