Kamchatka region (Petropavlovsk-Kamchatskiy), will change current time zone GMT+12, MSK+9 to current Magadan time zone ( GMT+11, MSK+8) 2.

Samara and Izhevsk in Russia will move to Moscow Time Zone on March 28, 2010
by Alexander Krivenyshev March 22, 2010

March 22, 2010

According to the Russian media, Prime Minister of Russia V. Putin signed a Resolution of the Government "ON THE APPLICATION IN THE TERRITORY OF THE UDMURT REPUBLIC SECOND TIME ZONE" 2 Russian regions (MSK +1, GMT+4): Samara region, capital Samara Udmurt Republic (Udmurtia), capital Izhevsk will move to Moscow Time Zone (MSK, GMT+3) on March 28, 2010. (in Russian) http://www.infox.ru/authority/state/2010/03/20/Rossiya_lishilas_odn.phtml Prime Minister of Russia V. Putin signed a Resolution of the Government "ON THE APPLICATION IN THE TERRITORY OF THE UDMURT REPUBLIC SECOND TIME ZONE" Draft Resolution of the Government could be found on The Ministry of Industry and Trade of the Russian Federation http://www.minprom.gov.ru/docs/ce/38 (in Russian) or http://www.worldtimezone.com/dst_news/dst_news_russia13.html As reference, both 2 regions (Udmurt Republic and Samara) are the only regions left in MSK +1 (GMT+4) Time Zone of Russia (blue color our Russian time zones map on) http://www.worldtimezone.com/time-russia24.php This is probably one of the transitional stage in the reshaping of Time Zones in Russia. As in the future, some regions from current time zone (MSK +2, GMT+5)- Perm, Kurgan, Chelyabinsk, Ekaterinburg (Yekaterinburg) probably will move to "empty" Russian time zone (MSK +1, GMT+4) Alexander Krivenyshev, http://www.worldtimezone.com

FW: Problems with timezone & altzone values
by Olson, Arthur David (NIH/NCI) [E] March 18, 2010

March 18, 2010

I'm forwarding this message from Madhusudanan Kandasamy, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado From: Madhusudanan Kandasamy [mailto:madhusudanan@in.ibm.com] Sent: Thursday, March 18, 2010 6:05 To: tz(a)lecserver.nci.nih.gov Subject: Problems with timezone & altzone values Hi Olson, As per POSIX standard timezone variable should be updated by tzset(), but its obvious that timezone values depends on what is the current time and during tzset() we won't be knowing the current time. So, for many countries, we are getting a wrong values for timezone and altzone for the current time. Hence is it possible to update the timezone and altzone values in localtime(), so atleast after calling the localtime we would be getting the correct values for both of these variables? The other solution would be to call time() in tzset(), and update the altzone, timezone variables in tzset itself. This will have little performance overhead, but we would be having a accurate values w.r.t current system time. This new feature could be under a #ifdef macros, so it can be enabled only for the people who are wants these variables to be updated in tzset itself but with a performance penalty. Also, is there any way available to get accurate values for these variables with the current version of the code? Thanks, Madhu. _________________________________ Madhusudanan Kandasamy AIX BOS Development, IBM Bangalore, EGL D block 6th Floor.

Feedback from Java - JSR-310
by Stephen Colebourne March 18, 2010

March 18, 2010

I am the spec lead for JSR-310, the project to enhance time handling in the Java JDK. I'd like to give some feedback/information to this project. Naming JSR-310 supports the possiblity of multiple sources of time zone information. The data here is considered to be the default. I've referred to this group as "TZDB" (rather than "Olson" as in some sources). Let me know if you're unhappy with the "TZDB" name. File format The format of the time zone data files (zic.8.txt) could do with some clarifications/simplifications. (ie. can the document be updated?) Rule - FROM - "The word minimum (or an abbreviation)" should be changed to "The word minimum or min". Similarly with maximum. At the moment, the spec is silent about what happens for the letter "m" which is a valid abbreviation of "minimum" and "maximum". The spec also allows oddities like "mini". Rule - TO - "the word only (or an abbreviation)" - please drop the abbreviation part. Only the full word is used in the data, never the abbreviation. Rule - IN - "Names the month in which the rule takes effect. Month names may be abbreviated.". This should specify that the month names are English. Currently, only the three letter abbreviation is used. The spec also allows oddities like "Januar" and ambiguities like "J". Can the spec be limited to just the 3 letter form? Rule ON - similar comment for day of week. Again the suppiled files only use the 3 letter abbreviated form. Can the spec be limited to just the 3 letter form? I didn't notice any specific comment about case - is the input case sensitive? thanks, Stephen

I am not on the list; any replies should be directed accordingly. Here's an item for tz-art.htm: an exchange from the play "Inherit the Wind" by Jerome Lawrence and Robert E. Lee (filmed in 1960 with Spencer Tracy as Drummond and Fredric March as Brady, and several other times): BRADY A fine biblical scholar, Bishop Usher, has determined for us the exact date and hour of the Creation. It occurred in the year 4004 B.C. DRUMMOND That's Bishop Usher's opinion. BRADY It's not an opinion. It is literal fact, which the good Bishop arrived at through careful computation of the ages of the prophets as set down in the Old Testament. In fact, he determined that the Lord began the Creation on the 23rd of October in the Year 4004 B.C. at -- uh, at 9 A.M.! DRUMMOND That Eastern Standard Time? (Laughter) Or Rocky Mountain Time? (More laughter) It wasn't daylight-saving time, was it? Because the Lord didn't make the sun until the fourth day! BRADY (Fidgeting) That is correct. DRUMMOND (Sharply) The first day. Was it a twenty-four-hour day? BRADY The Bible says it was a day. DRUMMOND There wasn't any sun. How do you know how long it was? BRADY (Determined) The Bible says it was a day. DRUMMOND A normal day, a literal day, a twenty-four-hour day? After a few more lines, Brady admits he doesn't know, and Drummond suggests that that "day" could have been 10 million years. -- Mark Brader, Toronto | In the affairs of this world men are saved, msb(a)vex.net | not by faith, but by the want of it. --Franklin

Currently the database has: # Ontario # From Paul Eggert (2006-07-09): # Shanks & Pottenger write that since 1970 most of Ontario has been like # Toronto. # Thunder Bay skipped DST in 1973. # Many smaller locales did not observe peacetime DST until 1974; # Nipigon (EST) and Rainy River (CST) are the largest that we know of. In the (Toronto) Globe and Mail for Saturday, 1955-09-24, in the bottom right corner of page 1, it says that Toronto will return to standard time at 2 am Sunday morning (which agrees with the database), and that: The one-hour setback will go into effect throughout most of Ontario, except in areas like Windsor which remains on standard time all year. Windsor is, of course, a lot larger than Nipigon. I only came across this incidentally. I don't know if Windsor began observing DST when Detroit did, or in 1974, or on some other date. By the way, the article continues by noting that: Some cities in the United States have pushed the deadline back three weeks and will change over from daylight saving in October. -- Mark Brader | "Oh, especially if it's accurate.

Perhaps this is not the best place to ask for it, but I got no answer from my local Sun Service representative (which I assume is Argentina). Could somebody point me where I could get the last version of the TZUpdater for Java, which includes tzdata2010e? Thanks, Carlos Raúl Perasso Asunción, Paraguay

Update time zone of the United States-Mexico border
by Ing. Obed Javier March 16, 2010

March 16, 2010

Hello, I'm using the google translator, I apologize if there is a misspelling; I know how to update the time zone (or to do ubuntu) to the border towns of Mexico with the United States and took effect on daylight saving time and yet time has not changed. In border cities, daylight saving time begins the second Sunday in March, and the rest of Mexico, the first Sunday in April. As a reference, put the story that supports this change: http://www.elmananarey.com/diario/noticia/tamaulipas/noticias/adelanta_fron… or (in english): http://translate.google.com/translate?js=y&prev=_t&hl=es&ie=UTF-8&layout=1&…

March 14, 2010

I have updated the maps of the TZ timezones presented at <http://efele.net/maps/tz>: - in sync with 2010e: introduction of America/Matamoros, America/Ojinaga, America/Santa_Isabel - the Kuril islands are now in Asia/Magadan rather than Asia/Sakhalin (thanks to Tobias Conradi for noticing the error) As a result, the Russia and world data files have changed. The other data files are identical. Eric.

Australia/Antarctica changes
by Steffen Thorsen March 10, 2010

March 10, 2010

We got these changes from the Australian Antarctic Division: - Macquarie Island will stay on UTC+11 for winter and therefore not switch back from daylight savings time when other parts of Australia do on 4 April. - Casey station reverted to its normal time of UTC+8 on 5 March 2010. The change to UTC+11 is being considered as a regular summer thing but has not been decided yet. - Davis station will revert to its normal time of UTC+7 at 10 March 2010 20:00 UTC. - Mawson station stays on UTC+5. In addition to the Rule changes for Casey/Davis, it means that Macquarie will no longer be like Hobart and will have to have its own Zone created.

The executive summary: asia Change time of day when Bangladesh DST starts and ends. australasia Change end of DST in Fiji in 2010. Add DST in Fiji in 2010/2011. Remove DST in Samoa in 2009/2010. Add DST in Fiji in 2010/2011. southamerica Change end date of Chile DST for 2010 only. Restate Paraguay DST rule for consistency.

Re: proposed time zone package chages--Bangladesh, Fiji, and Samoa
by Nobutomo Nakano March 4, 2010

It seems that the start time of Bangladesh DST is off 1 hour. > Rule Dhaka 2009 only - Jun 19 23:00 1:00 S > Rule Dhaka 2010 only - Jan 1 0:00 0 - > ! Rule Dhaka 2010 max - Mar 31 23:59 1:00 S > ! Rule Dhaka 2010 max - Oct 31 23:59 0 - DST will actually start at 22:59. And, newspaper below suggests that clock went back one hour at 11:59:00PM on 12-31-2009. This is actually consistent with what we heard from a customer in Bangladesh. http://www.thedailystar.net/newDesign/news-details.php?nid=119573 So the rule would look like: Rule Dhaka 2009 only - Jun 19 23:00 1:00 S Rule Dhaka 2009 only - Dec 31 23:59 0 - Rule Dhaka 2010 max - Mar 31 22:59 1:00 S Rule Dhaka 2010 max - Oct 31 23:59 0 - Best regards, -Nakano

proposed time zone package chages--Bangladesh, Fiji, and Samoa
by Arthur David Olson March 3, 2010

March 3, 2010

Below find proposed changes to two files in the time zone package, "asia" (changing the starting and ending time-of-day of DST in Bangladesh in 2010 and forward) and "australasia" (changing the end of DST in Fiji in 2010, adding DST in Fiji in 2010/2011, removing DST in Samoa in 2009/2010, and adding DST in Samoa in 2010/2011). If no problems are found, I plan to update the ftp version on 2010-03-08. I don't yet know whether Tunisia's abandonment of DST in 2009 was for that year only or establishes a new pattern, so I'm holding off on Tunisia changes for now. --ado ------- asia ------- *** /tmp/geta95 Wed Mar 3 17:56:45 2010 --- /tmp/getb95 Wed Mar 3 17:56:45 2010 *************** *** 1,4 **** ! # @(#)asia 8.51 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,4 ---- ! # @(#)asia 8.52 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 225,235 **** # until further notice."

No Tunisia DST in 2010 ?
by Philip.Pizzey＠sita.aero March 3, 2010

March 3, 2010

Hi there, many thanks for the continued excellent work from all the contributors to this list, much appreciated. Last year (2009) I believe that Tunisia suspended DST and the africa file was updated to reflect this change for 2009 only. The timeanddate.com entry for Tunis now states "No daylight saving time in 2010" though I have been unable to find any news reports or official announcements about this. Cheers, Phil. This document is strictly confidential and intended only for use by the addressee unless otherwise stated.

The Cabinet in Fiji has decided to end DST about a month early, on 2010-03-28 at 03:00. The plan is to observe DST again, from 2010-10-24 to sometime in March 2011 (last Sunday a good guess?).

I'm forwarding this message from Nobutomo Nakano, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado -----Original Message----- From: Nobutomo Nakano [mailto:nobutomo.nakano@Sun.COM] Sent: Friday, February 19, 2010 7:45 To: tz(a)lecserver.nci.nih.gov Subject: Bangladesh DST We received a report from Bangladesh saying that the start/end of Bangladesh DST is incorrect. Currently we have only the Bengali version of the official mail from BTRC which describes the following: "From 2010 each year when local standard time is about to reach March 31 at 10:59:00 PM clocks are turned forward 1 hour (11:59:00 PM) and when local daylight time is about to October 31 at 11:59:00 PM clocks are turned backward 1 hour (10:59:00 PM)." So, DST will start/end 1 minute earlier. Best regards, -Nakano

Currently we have only the Bengali version of the official mail from BTRC which describes the following: "From 2010 each year when local standard time is about to reach March 31 at 10:59:00 PM clocks are turned forward 1 hour (11:59:00 PM) and when local daylight time is about to October 31 at 11:59:00 PM clocks are turned backward 1 hour (10:59:00 PM)." So, DST will start/end 1 minute earlier. Best regards, -Nakano

core dump from within asctime_r()
by Robert Elz Feb. 18, 2010

Feb. 18, 2010

A NetBSD user reported fsck dumping core (when attempting to correct a corrupted filesystem). That's not nice. Upon investigation, the core dump turns out to be from within asctime_r() (as called via asctime() from ctime()). The code in fsck just does p = ctime(&t); where "t" contains one of the time fields from an (already determined to be corrupted, or we wouldn't be printing) inode. ctime() is (or course) just asctime(locatime(t)) locatime() can return NULL these days, and given a nonsense time value (which is quite likely under these circumstances), probably did, but asctime() doesn't expect anything but a valus "struct tm *" and will simply dereference NULL is NULL is returned from localtime() - instant core. It would be possible to make ctime() be tm = localtime(t); if (tm == NULL) return NULL; return asctime(tm); and in theory that would be adequate, but I'm actually going to suggest moving the fix into asctime() (into asctime_r() really of course), and have asctime_r() start if (timeptr == NULL) return NULL; I think that's a safer fix. Appended is the patch I suggest, made against the tzcode2009t sources (latest I believe.) kre

proposed time zone package changes--core dump avoidance
by Arthur David Olson Feb. 14, 2010

Feb. 14, 2010

Below find proposed changes to the time zone package: * asctime.c Set errno to EINVAL and return "??? ??? ?? ??:??:?? ????\n" if asctime_r is called with a NULL struct tm pointer. (Note that asctime_r is called by ctime_r and asctime; asctime is called by ctime.) * localtime.c Set errno to EINVAL and return WRONG if time1 is called with a NULL struct tm pointer; avoid dereference if a NULL struct tm pointer is passed to timelocal, timegm, or timeoff. (Note that time1 is called by mktime, timegm, and timeoff; mktime is called by timelocal.) Barring problems, expect these changes to show up in the ftp package on 2010-02-16 (a day later than usual given a U. S. federal holiday). --ado ------- asctime.c ------- *** /tmp/geta26934 Sat Feb 6 13:23:25 2010 --- /tmp/getb26934 Sat Feb 6 13:23:25 2010 *************** *** 11,17 **** #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)asctime.c 8.2"; #endif /* !defined NOID */ #endif /* !defined lint */ --- 11,17 ---- #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)asctime.c 8.3"; #endif /* !defined NOID */ #endif /* !defined lint */ *************** *** 91,96 **** --- 91,100 ---- char year[INT_STRLEN_MAXIMUM(int) + 2]; char result[MAX_ASCTIME_BUF_SIZE]; + if (timeptr == NULL) { + errno = EINVAL; + return "??? ??? ?? ??:??:?? ????\n"; + } if (timeptr->tm_wday < 0 || timeptr->tm_wday >= DAYSPERWEEK) wn = "???"; else wn = wday_name[timeptr->tm_wday]; ------- localtime.c ------- *** /tmp/geta26952 Sat Feb 6 13:23:25 2010 --- /tmp/getb26952 Sat Feb 6 13:23:25 2010 *************** *** 5,11 **** #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)localtime.c 8.9"; #endif /* !defined NOID */ #endif /* !defined lint */ --- 5,11 ---- #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)localtime.c 8.10"; #endif /* !defined NOID */ #endif /* !defined lint */ *************** *** 1889,1894 **** --- 1889,1898 ---- int types[TZ_MAX_TYPES]; int okay; + if (tmp == NULL) { + errno = EINVAL; + return WRONG; + } if (tmp->tm_isdst > 1) tmp->tm_isdst = 1; t = time2(tmp, funcp, offset, &okay); *************** *** 1960,1966 **** timelocal(tmp) struct tm * const tmp; { ! tmp->tm_isdst = -1; /* in case it wasn't initialized */ return mktime(tmp); } --- 1964,1971 ---- timelocal(tmp) struct tm * const tmp; { ! if (tmp != NULL) ! tmp->tm_isdst = -1; /* in case it wasn't initialized */ return mktime(tmp); } *************** *** 1968,1974 **** timegm(tmp) struct tm * const tmp; { ! tmp->tm_isdst = 0; return time1(tmp, gmtsub, 0L); } --- 1973,1980 ---- timegm(tmp) struct tm * const tmp; { ! if (tmp != NULL) ! tmp->tm_isdst = 0; return time1(tmp, gmtsub, 0L); } *************** *** 1977,1983 **** struct tm * const tmp; const long offset; { ! tmp->tm_isdst = 0; return time1(tmp, gmtsub, offset); } --- 1983,1990 ---- struct tm * const tmp; const long offset; { ! if (tmp != NULL) ! tmp->tm_isdst = 0; return time1(tmp, gmtsub, offset); }

Wrong DST rules for Mauritius
by Leonid A. Movsesjan Jan. 20, 2010

Jan. 20, 2010

Good day! There are two rules for Mauritius in current version of timezone/africa: Rule Mauritius 2008 max - Oct lastSun 2:00s 1:00 S Rule Mauritius 2009 max - Mar lastSun 2:00s 0 - It's wrong, because Mauritius used DST only in 2008/2009, prooflinks: http://www.timeanddate.com/news/time/mauritius-daylight-saving-time.html http://www.timeanddate.com/news/time/mauritius-dst-will-not-repeat.html So, rules should be: Rule Mauritius 2008 only - Oct lastSun 2:00s 1:00 S Rule Mauritius 2009 only - Mar lastSun 2:00s 0 - or something like that. -- Best regards, Leonid A. Movsesjan

Mexican border DST
by Olson, Arthur David (NIH/NCI) [E] Jan. 20, 2010

Jan. 20, 2010

I've found this government-site web page... http://dof.gob.mx/nota_detalle.php?codigo=5127480&fecha=06/01/2010 ...indicating that Ensenada is indeed to use US DST rules starting in 2010; I'll adjust the proposed time zone package changes accordingly and hope to send something out later today. --ado

tz isdst

Jan. 20, 2010

I am asking for a way to give zdump a timezone, date and hour, so zdump (or other command) can give me the "isdst". Another way could be to give time zone (or Country and city), date and hour and get the UTC and "isdst". Should it be possible? Thanks in advance.

The file... ftp://elsie.nci.nih.gov/pub/tzdata2010a.tar.gz ...is now available; this reflects only the changes to Dhaka circulated recently on the time zone mailing list. I'm still trying to determine just what northern-Mexico areas are to observe US DST starging in 2010, and there's at least Mauritius work to do; expect tzdata2010b.tar.gz in a week or two. --ado

proposed time zone package changes for Dhaka and Mexico
by Arthur David Olson Jan. 13, 2010

Jan. 13, 2010

Below find proposed changes to the time zone package. The executive summary: asia Revert 2009 start of DST in Dhaka to correct date. Make Dhaka "AT" fields consistent with others. backward Remove Tijuana/Ensenada link northamerica Split off Mexican cities (near US border) that are to follow US rules starting in 2010. Tijuana splits into Tijuana and Ensenada. Chihuahua splits into Chihuahua and Ojinaga. Monterrey splits into Monterrey and Matamoros. (And...a cosmetic change to Mexico_City while we're in the neighborhood.) zone.tab Change Mexico entries to reflect border city changes. Other Mexican border cities are switching to US rules; both "northamerica" and "zone.tab" list the cities. If these pass muster they'll appear in the ftp "data" bundle on 2010-01-18 --ado diff -r -c old/asia new/asia *** old/asia Sat Dec 26 08:32:28 2009 --- new/asia Wed Jan 6 10:21:32 2010 *************** *** 1,4 **** ! # @(#)asia 8.50 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,4 ---- ! # @(#)asia 8.51 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 226,235 **** # establishment of a rule. # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S !

Hi, I notice a little nuance that would be nice be corrected, between 1963-10-23 and 1963-12-9 in brazil only Minas Gerais , Espirito Santo, Rio de Janeiro and Sao Paulo had sumer time. this can be verified in the links. http://pcdsh01.on.br/DecHV.html http://pcdsh01.on.br/HV52700.htm http://pcdsh01.on.br/HV53071.htm I propose separate Zone America/Sao_Paulo in one more zone America/Brasilia, the configuration would be like: # Minas Gerais (MG), Espirito Santo (ES), # Rio de Janeiro (RJ), Sao Paulo (SP) Zone America/Sao_Paulo -3:06:28 - LMT 1914 -3:00 Brazil BR%sT 1963 Oct 23 00:00 -3:00 1:00 BRST 1964 -3:00 Brazil BR%sT # Goias (GO), Distrito Federal (DF), Parana (PR), # Santa Catarina (SC), Rio Grande do Sul (RS) Zone America/Brasilia -3:06:28 - LMT 1914 -3:00 Brazil BR%sT 1963 Dec 9 00:00 -3:00 1:00 BRST 1964 -3:00 Brazil BR%sT Ps.:Sorry my poor english

London and Dublin zone definitions
by Danvin Ruangchan Dec. 17, 2009

Dec. 17, 2009

Hey all, Is there a reason why the Europe/London and Europe/Dublin Zone definitions are outside the "Europe" section that starts on line # 449 in the "europe" data file? For consistency sake, shouldn't those two sections be moved under the "Europe" section where the DST Rule for "EU" is defined? thanks danvin

Help With Understanding the Binary Files
by Bill Seymour Dec. 14, 2009

Dec. 14, 2009

Could somebody please help me interpret the tz binary files? I'm having trouble understanding what to do with the two arrays that follow the leap second array. 1. tzfile.h says that they're "indexed by type"; but I don't see anything in the "type" (which I take to mean what tzfile.5 calls "struct ttinfo") that could be used as such an index. Does "indexed by type" mean "having the same index as the type", in other words, the value from the array following the transition time array? 2. tzfile.h seems to imply that these booleans indicate how I should interpret the values in the array of transition times. Is that correct? If so, how do I calculate standard time while DST is being observed given that the SAVE column in the Rule has been lost? Do I assume that the offset for DST is always exactly 1 hour? What about solar89, etc.? 3. tzfile.5 says that these "are used when a time zone file is used in handling POSIX-style time zone environment variables." Does that mean that the "transition times" are the ones in the TZ variable, not the array of transition times in the file (so my question 2 is moot)? I'm very confused. 8-( Thanks, --Bill Seymour

This comes from tzdata2009s, southamerica file The rules are # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Brazil 2008 max - Oct Sun>=15 0:00 1:00 S Rule Brazil 2008 2011 - Feb Sun>=15 0:00 0 - Rule Brazil 2012 only - Feb Sun>=22 0:00 0 - Rule Brazil 2013 2014 - Feb Sun>=15 0:00 0 - The Timezone # # east Amazonas (AM): Boca do Acre, Jutai, Manaus, Floriano Peixoto # The great circle line from Tabatinga to Porto Acre divides # east from west Amazonas. Zone America/Manaus -4:00:04 - LMT 1914 -4:00 Brazil AM%sT 1988 Sep 12 -4:00 - AMT 1993 Sep 28 -4:00 Brazil AM%sT 1994 Sep 22 -4:00 - AMT >From what I understand from the above, America/Manaus does not observe DST ever since Sep 22, 1994. However, looking at the Microsoft Timezone definition [Dec 2009 update] for (GMT -4:00) Manaus [Central Brazilian Standard Time] the timezone observe DST from 3rd Saturday of October 23:59:59 to 3rd Saturday of February, 23:59:59. Also, another non-official site seems to imply the same: [http://www.icfsi2007.com/city_more.php will show Time Manaus Time Zone is 1 hour less than Brasilia, Sao Paulo or Rio de Janeiro Time Zone (GMT - 03:00), four hours behind of Greenwich Mean Time (GMT), except during the period between late October and the end of February, when daylight saving time is in force (GMT - 05:00 hours). ] So either a) I do not interpret the timezone rules properly for America/Manaus, and there is a DST being observed there. If so, please let me know how I should read the above rules/timezone information. b) Microsoft timezone is incorrect c) Olson data is incorrect d) The Microsoft timezone [(GMT -4:00) Manaus - Central Brazilian Standard Time] does not correspond to the Olson's America/Manaus timezone Your opinion would be appreciated Thanks -Alain Petit

Given the note about how "putting ethnic labels on the time zones may be somewhat divisive in an already very unhappy and divisive time," can someone come up with a better approach to the Xinjiang situation than the "first pass" sent out on the list last month? I'll hold off on making any changes until we have something better. --ado

first pass at Uyghur time

Below find a first pass at changes to "zone.tabb" and "asia" to handle Uyghur variants of time in China.

Re: Xinjiang
by Olson, Arthur David (NIH/NCI) [E] Nov. 20, 2009

Nov. 20, 2009

As I understand it, there are two groups (Han and Uyghur) in two different current time zone regions ("Asia/Urumqi" and "Asia/Kashgar") using different times. A blessing: nobody involved currently does daylight saving. Since DST is not in effect, a workaround is to set the environment variable, either... TZ=XJT-6 ...or... TZ=XST-6 ...to get the desired effect. Here are questions to be answered prior to setting up zones in the "asia" file: 1. What's the English translation of the Han name of the city with the largest Han population in Asia/Urumqi? 2. What's the English translation of the Han name of the city with the largest Han population in Asia/Kashgar? 3. What's the English translation of the Uyghur name of the city with the largest Uyghur population in Asia/Urumqi? 4. What's the English translation of the Uyghur name of the city with the largest Uyghur population in Asia/Urumqi? 5. When exactly did the Asia/Urumqi Uyghurs start using their own distinct time? 6. When exactly did the Asia/Kashgar Uyghurs start using their own distinct time? The path forward depends on the answers to the above questions. --ado

Asia/Krasnoyarsk GMT offset wrong?

I received a bug report with the following claim for this time zone: > Expected Results: > 1. If Asia/Krasnoyarsk is in standard time, should be 21600 (GMT +6) > 2. If Asia/Krasnoyarsk is in daylight savings time, should be 25200 (GMT +7) > > Actual Results: > 1. Standard time returns 25200 (GMT +7) > 2. Daylight savings time returns 28800 (GMT +8) > I see in the europe file (today’s version, 2009s) that the base offset is indeed +7. So, does anyone know if this is correct?

It is called Simple Timer + Clocks, and the homepage is http://simpletimerclocks.mozdev.org/ It has various functions including: # display your local clock # track the local time in locations around the world # receive notifications at specific times of the day (using your local time, or local time in other timezones) # receive notifications on specific dates (ie. calendar function) # count up from zero # count down from any time (less than 24 hours). You can set as many timers as you want # event logging for completed count ups, count downs, notifications and calendar events It existed for a while on mozdev.org, just recently I made it available for download through AMO. Regards, George Bradt

Updated efele.net/tz maps
by Eric Muller Nov. 11, 2009

Nov. 11, 2009

I have updated the maps of the TZ timezones presented at <http://efele.net/maps/tz>: - in sync with 2009r - antarctica is now handled (that leaves only Greenland that is not dealt with) - better processing to produce the maps, resulting in better quality - addition of terms of use (everything is CC0; i.e. whatever I had a right to is now in the public domain) I am sure there are some glitches; please let me know. Enjoy, Eric.

Xinjiang Time
by Luther Ma Nov. 1, 2009

Nov. 1, 2009

I am new to the list but would like to make a proposal for Xinjiang time. I have looked through previous posts about Xinjiang and would agree with the paradoxical statements that: 1. All of China is on one time zone, (Zhe Su Jun 26, 2006) and 2. Xinjiang has another, governmentally recognized time zone. (Thomas S. Mullaney Feb 12, 2008) Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time, but have no need of it. All planes, trains, and schools function on what is called "Beijing time". When Han make an appointment in Chinese they implicitly use Beijing time. On the other hand, ethnic Uyghurs, who make up about half the population of Xinjiang, typically use "Xinjiang time" which is two hours behind Beijing time, or UTC +0600. The government of the Xinjiang Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as local governments such as the Urumqi city government use both times in publications, referring to what is popularly called Xinjiang time as "Urumqi time". When Uyghurs make an appointment in the Uyghur language they almost invariably use Xinjiang time. (Their ethnic Han compatriots would typically have no clue of its widespread use, however, because so extremely few of them are fluent in Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.) Because there presently is no time localization for a large Uyghur population who set their watches to Xinjiang time, I propose that the last line of the "Asia/Urumqi" and "Asia/Kashgar" entries be changed so that the entries read: Zone Asia/Urumqi 5:50:20 - LMT 1928 # or Urumchi 6:00 - URUT 1980 May # Urumqi Time 6:00 - XJT #Xinjiang Time and Zone Asia/Kashgar 5:03:56 - LMT 1928 # or Kashi or Kaxgar 5:30 - KAST 1940 # Kashgar Time 5:00 - KAST 1980 May 6:00 - XJT #Xinjiang Time (I did not include the PRC rule. As with the rest of China there was a brief interval ending in 1990 or 1991 when summer time was in use. The confusion was severe, with the province not having dual times but four times in use at the same time. Some areas remained on standard Xinjiang time or Beijing time and others moving their clocks ahead.) This proposed correction would reflect usage for at least the last thirty years and would be a great help to Uyghurs who are becoming increasingly technologically sophisticated. (They routinely use Uyghur localized operating systems and localized cell phones.) XJT would also be preferable to URUT as this reflects standard usage as well as correctly reflects the time zone for an area (in this case, the autonomous region) and not just a city. I don't believe that this would cause the slightest difficulty for ethnic Han population, as they would typically set their phones and computer time to Beijing. Some may only be a bit surprised that a separate Xinjiang exists. I, myself, speak from being present in Xinjiang off and on since the 80's; from my own observations as well as from asking informants who came from outlying areas. Unfortunately, Internet documentation of the actual law is presently hard to get. Immediately after the events of earlier this summer, Internet in Xinjiang was cut and is still out, so many Xinjiang sites are unavailable. Below, though, is an example of an official website using of Urumqi time. The first few lines of the Google translation of http://www.fjysgl.gov.cn/show.aspx?id=2379&cid=39 (retrieved 2009-10-13) > Urumqi fire seven people are missing the alleged losses of at least > 500 million yuan > > (Reporter Dong Liu) the day before 20:20 or so (Urumqi Time 18:20), > Urumqi City Department of International Plaza Luther Qiantang River > burst fire. As of yesterday, 18:30, Urumqi City Fire officers and > men have worked continuously for 22 hours, .... > -Lude (Luther) Ma PS This request was actually prompted by tzdata being updated for summer time in Dhaka. Previously Asia/Dhaka was a good work-around for for me and others not having a proper Xinjiang time. The update has caused me to ask if there might be a better solution.

Syria end of DST error in tz
by Thomas Nash Oct. 31, 2009

Oct. 31, 2009

Syria went to winter time this year at Midnight Thursday night (October 29-30) **not** Saturday night Oct 31-Nov1 as the tz data base presently indicates. We were in Damascus and had a flight on Friday morning -- so we had to get this right. Emirate airlines appeared to know about this at least several months in advance as they had adjusted their flight schedules for this date when we bought tickets in June. Probably the reason for this change is that Friday is the day off, equivalent of our Sunday in Islamic countries. This may become common in other Islamic countries. Regards from Ajman in the UAE...

Oct. 26, 2009

The file... ftp://elsie.nci.nih.gov/pub/tzdata2009p.tar.gz ...is now available; this reflects the Argentina (including San Luis) changes circulated on the time zone mailing list last week (with the correction from Mariano Absatz). Now that 2009p has all the changes affecting current stamps, I'll be moving on to stuff affecting past and future time stamps. Expect a 2009q next week, but if you're only interested in current stuff, 2009p should do the job. --ado

FW: Incorrect historial DST rule for Hong Kong

Accoring to the DST record from Hong Kong Observatory (actually, it is not a observatory, but the official meteorological agency of HK, and also serves as the official timing agency), there are some missing and incorrect rules.

Mistakes I found: - DST records before 1946 are missing (note: during 1942-1945 (WWII) Hong Kong is under Japanese occupation, and Hong Kong is put into DST for whole year, which would make HKT "in sync" with Japan. For 1941 you can assume the start/end time is 3:30, which should be a reasonale guess. - The end date of 1952 end time is incorrect. The current tz rule implies the end date is Oct 26, but the actual end date is Oct 25. - There is extra DST period during Dec 30 1973 to 20 Oct 74.

tzdata2009o - southamerica
by Pablo Nazar Oct. 21, 2009

Oct. 21, 2009

Regards, The Argentinian DST time change for Oct-19 was *not* done in the whole country; several Provinces did *not* change the clocks. Is this the reason why tzdata2009o doesn't contain these changes? (just guessing, I need to ask) Thanks -- Pablo Nazar

Argentina DST change.
by Veiga Jorge Oct. 21, 2009

Oct. 21, 2009

As you may know, the time zone change to DST time in Argentina was not realized last sunday October 18th. Even though the file southamerica file in current tzdata compilation is right, the DST change in my country is only taken yearly under a political presidential decreet (per decreet basis). I hope this information becomes usefull for you. Regards, Jorge Veiga Telefónica de Argentina * mailto:veigaj@telefonica.com.ar

New initiative for DST in Juarez, Chihuahua (Mexico)
by Alexander Krivenyshev Oct. 19, 2009

Oct. 19, 2009

There is a new initiative or intention to redeem the proposal ("frozen" in the previous legislature) to approve the new DST schedule in the municipality of Juarez, Chihuahua state (Mexico): (Spanish) http://www.diario.com.mx/nota.php?notaid=26d0da68d4e7efd3e7c7f4fed0b6c466 (Spanish) A eso se le añadiría “en el caso del municipio de Juárez, en el estado de Chihuahua, esta aplicación surtirá efecto desde las dos horas del segundo domingo de marzo y concluirá a las dos horas del primer domingo de noviembre”. or (English) http://www.worldtimezone.com/dst_news/dst_news_mexico05.html …would add "in the municipality of Juarez, Chihuahua State, the DST application shall take from two hours the second Sunday in March and end at two hours the first Sunday in November." DST starts in El Paso, USA (second Sunday in March) 3 weeks before DST starts in Juarez, Mexico (First Sunday in April). DST ends in El Paso, USA (first Sunday in November) 1 week after DST ends in Juarez, Mexico (Last Sunday in October). 4 weeks of DST mismatch in USA and Mexico (3 weeks in spring and 1 week in autumn) is affecting communities on both sides of the border. -------------------- Alexander Krivenyshev (World Time Zone) http://www.worldtimezone.com

Regarding Argentina/San_Luis
by Mariano Absatz - El Baby Oct. 18, 2009

Oct. 18, 2009

Hi, this one I missed... Besides today's breaking news about Argentina not changing to DST this summer, the Province of San Luis is a case in itself. The Law at http://www.diputadossanluis.gov.ar/diputadosasp/paginas/verNorma.asp?NormaI… is ambiguous because establishes a calendar from the 2nd Sunday in October at 0:00 thru the 2nd Saturday in March at 24:00 and the complement of that starting on the 2nd Sunday of March at 0:00 and ending on the 2nd Saturday of March at 24:00. This clearly breaks every time the 1st of March or October is a Sunday. IMHO, the "spirit of the Law" is to make the changes at 0:00 on the 2nd Sunday of October and March. The problem is that the changes in the rest of the Provinces that did change in 2007/2008, were made according to the Federal Law and Decrees that did so on the 3rd Sunday of October and March. In fact, San Luis actually switched from UTC-4 to UTC-3 last Sunday (October 11th) at 0:00. So I guess a new set of rules, besides "Arg", must be made and the last America/Argentina/San_Luis entries should change to use these... I'm enclosing a patch that does what I say... regretfully, the San Luis timezone must be called "WART/WARST" even when most of the time (like, right now) WARST == ART... that is, since last Sunday, all the country is using UTC-3, but in my patch, San Luis calls it "WARST" and the rest of the country calls it "ART". The patch includes the previous patch from Margarita. Of course, there is no indication that any time soon, the Federal Government says anything about what will happen next year... probably they will decide by mid-October 2010 :-( Regards. -- Mariano Absatz - "El Baby" baby(a)baby.com.ar www.clueless.com.ar -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Justify my text?

Talks about DST in Nepal
by Steffen Thorsen Oct. 16, 2009

Oct. 16, 2009

According to the Nepali Times, there has been a discussion about observing DST in Nepal: "Daylight saving time (DST) has been discussed before in the Nepal Electricity Authority and the Ministry of Environment, but plans have since gathered dust. If enacted, DST would delay sunset and sunrise by 1 hour and 15 minutes, reducing light use during evening peak hours" Also from the article, it seems that the 15 minute difference to India is not that popular, although having DST will not exactly make it easier (1.5 hour difference to India): http://www.nepalitimes.com/issue/2009/10/16/Nation/16397 Best regards, Steffen Thorsen - timeanddate.com

proposed time zone package changes for Samoa (comments), Bangladesh, and Pakistan
by Arthur David Olson Oct. 14, 2009

Oct. 14, 2009

At the end of this message are proposed changes to time zone files, summarized here: asia Bangladesh does not go off DST in 2009 Pakistan Goes off DST November 1 2009 (and in future years) australasia Samoa information on Samoa NOT starting DST in 2009 (comments only) I've only included changes involving 2009; other data changes (as well as tz-art additions) are in the pipeline. The adoption of "permanent" DST in Bangladesh means there's another place that can't be represented by a POSIX time zone environment variable; this may cause some grief. We may want to change the trailing... 6:00 1:00 BDST ...line for Bangladesh to... 5:00 - BDST ...either in the short term or the long term. If no one finds problems, expect these changes to show up on the ftp site on 2009-10-19. --ado ------- asia ------- *** /tmp/geta23160 Wed Oct 14 16:50:00 2009 --- /tmp/getb23160 Wed Oct 14 16:50:00 2009 *************** *** 1,5 **** # <pre> ! # @(#)asia 8.41 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)asia 8.42 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 172,183 **** # # No DST end date has been announced yet. ! # From Arthur David Olson (2009-07-11): ! # Arbitrarily end DST at the end of 2009 so that a POSIX-sytle time zone string ! # can appear in the Dhaka binary file and for the benefit of old glibc ! # reimplementations of the time zone software that mishandle permanent DST. ! # A change will be required once the end date is known. # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Dhaka 6:01:40 - LMT 1890 5:53:20 - HMT 1941 Oct # Howrah Mean Time? --- 172,202 ---- # # No DST end date has been announced yet. ! # From Alexander Krivenyshev (2009-09-25): ! # Bangladesh won't go back to Standard Time from October 1, 2009, ! # instead it will continue DST measure till the cabinet makes a fresh decision. ! # ! # Following report by same newspaper-"The Daily Star Friday": ! # "DST change awaits cabinet decision-Clock won't go back by 1-hr from Oct 1" ! # <a href="http://www.thedailystar.net/newDesign/news-details.php?nid=107021"> ! # http://www.thedailystar.net/newDesign/news-details.php?nid=107021 ! # </a> ! # or ! # <a href="http://www.worldtimezone.com/dst_news/dst_news_bangladesh04.html"> ! # http://www.worldtimezone.com/dst_news/dst_news_bangladesh04.html ! # </a> + # From Steffen Thorsen (2009-10-13): + # IANS (Indo-Asian News Service) now reports: + # Bangladesh has decided that the clock advanced by an hour to make + # maximum use of daylight hours as an energy saving measure would + # "continue for an indefinite period." + # + # One of many places where it is published: + # <a href="http://www.thaindian.com/newsportal/business/bangladesh-to-continue-indefin…"> + # http://www.thaindian.com/newsportal/business/bangladesh-to-continue-indefin… + # </a> + # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Dhaka 6:01:40 - LMT 1890 5:53:20 - HMT 1941 Oct # Howrah Mean Time? *************** *** 186,193 **** 6:30 - BURT 1951 Sep 30 6:00 - DACT 1971 Mar 26 # Dacca Time 6:00 - BDT 2009 Jun 19 23:00 # Bangladesh Time ! 6:00 1:00 BDST 2010 ! 6:00 - BDT # Bhutan # Zone NAME GMTOFF RULES FORMAT [UNTIL] --- 205,211 ---- 6:30 - BURT 1951 Sep 30 6:00 - DACT 1971 Mar 26 # Dacca Time 6:00 - BDT 2009 Jun 19 23:00 # Bangladesh Time ! 6:00 1:00 BDST # Bhutan # Zone NAME GMTOFF RULES FORMAT [UNTIL] *************** *** 1684,1696 **** # http://www.thenews.com.pk/updates.asp?id=87168 # </a> # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Pakistan 2002 only - Apr Sun>=2 0:01 1:00 S Rule Pakistan 2002 only - Oct Sun>=2 0:01 0 - Rule Pakistan 2008 only - Jun 1 0:00 1:00 S Rule Pakistan 2008 only - Nov 1 0:00 0 - !

Kemerovo region (Russia) will change time zone from (KRA) UTC+07 to (NOV) UTC+06
by Alexander Krivenyshev Oct. 13, 2009

Oct. 13, 2009

Kemerovo oblast' (Kemerovo region)- in Russia will change current time zone on March 28, 2010: from current Russia Zone 6 - Krasnoyarsk Time Zone (KRA) UTC +0700 to Russia Zone 5 - Novosibirsk Time Zone (NOV) UTC +0600 This is according to Government of Russia decree # 740, on September 14, 2009 "Application in the territory of the Kemerovo region the Fifth time zone." ("Russia Zone 5" or old "USSR Zone 5" is GMT +0600) Russian Government web site (Russian language) http://www.government.ru/content/governmentactivity/rfgovernmentdecisions/a… e/2009/09/14/991633.htm or Russian-English translation by WorldTimeZone.com with reference map to local region and new Russia Time Zone map after March 28, 2010 http://www.worldtimezone.com/dst_news/dst_news_russia03.html Thus, when Russia will switch to DST on the night of March 28, 2010- Kemerovo region (Kemerovo oblast') will not change the clock. As a result , Kemerovo oblast' will be in the same time zone as Novosibirsk, Omsk, Tomsk, Barnaul and Altai Republic. Alexander Krivenyshev (World Time Zone), http://www.worldtimezone.com

Pakistan data incorrect?
by Andy Heninger Oct. 12, 2009

Oct. 12, 2009

Pinging the Pakistan question again, the current (2009n) data for Pakistan appears to be incorrect for the date for the end of daylight savings time for this year, 2009n says Rule Pakistan 2009 only - Oct 1 0:00 0 - Should be Rule Pakistan 2009 only - Nov 1 0:00 0 - I've independently received reports that Pakistan is still on Daylight time, but if someone located there could confirm it, that would be good. (I'm not there.) And then, of course, the data wants to be updated. Thanks, -- Andy

Here is reply from Consulate-General of Samoa in New Zealand --------------------------- Consul General consulgeneral(a)samoaconsulate.org.nz Talofa Alexander, Thank you for your sympathy for our country but at this time we have not been informed about the Daylight Savings Time Change. Most Ministries in Apia are closed or relocating due to weather concerns. When we do find out if they are still proceeding with the time change we will advise you soonest.

New home for time zone stuff by 2012?
by Olson, Arthur David (NIH/NCI) [E] Sept. 8, 2009

Sept. 8, 2009

I'll be eligible to start drawing a pension in mid-2012. Since I'm accustomed to slow-moving Quaker process, that makes it time to get serious about finding a new home for time zone stuff. There are several pieces of the puzzle (some of which haven't seen much work of late): Data maintenance Data distribution Code maintenance Code distribution Mailing list maintenance Mailing list hosting Standards work (for example, tweaking POSIX TZ environment variables so Godthab can be represented) Code enhancement (for example, year zero work and Julian calendar work) There are different types of landing place: Governmental organizations Non-governmental organizations Commercial entities Volunteers Everything could be moved under one new roof or different pieces might go different places. While I'm happy to continue time zone work in the future, I also understand that it may be best for others to do the work. Anyone? Bueller? --ado

Proposed time zone package changes for West Bank (comment only) and Samoa
by Arthur David Olson Aug. 31, 2009

Aug. 31, 2009

Below are proposed changes to the "australasia" file to reflect use of DST in Samoa in 2009-2010, as well as a comment added to the "asia" file on DST in the West Bank this year. The Samoa change may need tweaking once the actual legislation (and the hour at which the changes take place) is in hand; there may be a need to tweak the "asia" file once Gaza's DST end in 2009 is determined. If no problems are found, these changes will appear in the ftp packages on 2009-09-07. Some long-term work is needed on the differences between West Bank time and Gaza time. --ado ------- australasia ------- *** /tmp/geta10880 Mon Aug 31 12:25:41 2009 --- /tmp/getb10880 Mon Aug 31 12:25:41 2009 *************** *** 1,5 **** # <pre> ! # @(#)australasia 8.12 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)australasia 8.13 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 443,452 **** # http://www.worldtimezone.com/dst_news/dst_news_samoa01.html # </a> Zone Pacific/Apia 12:33:04 - LMT 1879 Jul 5 -11:26:56 - LMT 1911 -11:30 - SAMT 1950 # Samoa Time ! -11:00 - WST # Samoa Time # Solomon Is # excludes Bougainville, for which see Papua New Guinea --- 443,468 ---- # http://www.worldtimezone.com/dst_news/dst_news_samoa01.html # </a> + # From Steffen Thorsen (2009-08-27): + # Samoa's parliament passed the Daylight Saving Bill 2009, and will start + # daylight saving time on the first Sunday of October 2009 and end on the + # last Sunday of March 2010.

The Calendaring and Scheduling Consortium (CalConnect), through a number of activities over time, has demonstrated an active interest in addressing problems related to timezones for calendaring and scheduling systems for a while. The standards in this space, namely iCalendar, were developed by the Internet Engineering Task Force (IETF). A number of issues have spurred this work within CalConnect, including (but not limited to) the US EDST changes from 2007. As "consumers" of timezone data (rather than "producers" - which relates to the job done by the community represented by this mailing list, tz(a)elsie.nci.nih.gov) we are eager to see a reliable, timely and secure process for handling timezones. In CalConnect's Timezone Technical Committee (TC), we are presently developing a timezone service protocol that will allow for direct updates of client systems, rather than relying on the current process where systems typically get updated via OS upgrades, if at all. As part of this effort, we are also developing a generic timezone description format in XML so that interchange of timezone data can be done efficiently, and so that we can include structured meta-data like KML for boundary information. CalConnect would like to see a formal "standardization" of timezone names with a registry. This issue has been a problem in the iCalendar space where presently it is difficult to rely on a timezone definition with a given name, often resulting in interoperability problems. CalConnect would like to see timezone data passed "by reference" rather than "by value" for efficiency purposes (iCalendar requires that a VTIMEZONE component always be included in the iCalendar data stream when a timezone is referenced by an event). Earlier this year, CalConnect hosted a timezone workshop at one of its face-to-face Roundtables. The primary focus of the workshop was to discuss the problem statement and development of the protocol, data format and registry process. Since then we have also initiated discussions in the IETF on these topics. As "consumers" of timezone data CalConnect feels strongly about the need for these improvements. None of this necessarily impacts the process of "producing" timezone data as carried out by this list's community. Nonetheless, we care greatly about the "production" process because we have to rely on this data. We have informally discussed within the CalConnect Timezone TC what we would like to see for the future of the timezone data. We have not come to any firm conclusions as to the best way forward. Mr. Olson's email, therefore, comes as a timely reminder that this needs to be addressed now. Possible options (as already indicated by Mr. Olson) include: - Moving it to an "open source" location (such as SourceForge, which has been already suggested) - Setting up some kind of open consortium of interested parties to manage timezone data - Moving responsibility to an existing standards body (e.g., the IETF or the Internet Society - ISOC) - Moving responsibility to a government entity (e.g., the UN) Unfortunately, this debate can easily get mired in "politics" rather than technical issues. e.g., who gets to control the data, how is the service paid for, who gets to contribute. At the end of the day, CalConnect favors an approach which results in the least amount of disruption. The open community process developed via this list's community has clearly been a success, and should be considered as a potential model going forward. CalConnect considers tightening up of the security of the timezone data to be essential. Given that many systems rely on the data being produced, we collectively need a secure distribution (i.e. a secure, reliable server, signed data etc). Whilst there have not been any obvious "attacks" against timezone data, one cannot assume there won't be any in the future. This is a propitious time to achieve consensus on the best way to secure the data. This may very well impose additional requirements on hosting the data in the future, e.g., cost of maintaining the server, signing certificates etc). CalConnect looks forward to the discussions on this issue, and would like to hear the thoughts of other members of this community.

John's most recent message seems to indicate that the latest "africa" file has the correct transiton time for Egypt. --ado From: John Martin [mailto:john.d.martin.iii@gmail.com] Sent: Monday, August 24, 2009 11:15 To: Olson, Arthur David (NIH/NCI) [E] Cc: tz(a)elsie.nci.nih.gov Subject: Re: FW: source file correction for tzdata (egypt end of daylight savings) I live in Cairo. The time changed before the month of Ramadan began on Saturday 22 August 2009. The actual date of the change was midnight between Thursday 20 and Friday 21, which was not expected before it was announced by the government this week. Prior to that, it had been expected that we would switch after the Islamic month of Ramadan toward the end of September. The reason for the change is that Muslims here fast (no food, drink, smoking or sex) during daylight hours, so this effectively moves the end of fasting every day an hour earlier. They will likely not continue this past this year, but for the past few years, they have switched the time from DST right before Ramadan for this same reason. The reason that this keeps changing is that the Islamic calendar and the gregorian calendar do not line up. Instead, because the Muslim calendar bases the months on the moon phase, the beginning date for each month (including Ramadan) move earlier each year.

Hi, Does anyone know of an update for the end of DST in Africa/Cairo? According to the latest tzdata2009k.tar.gz, DST will end on September 24, 2009. However, time and date have August 20, 2009: http://www.timeanddate.com/worldclock/clockchange.html?n=53 We have confirmed with several properties in Cairo that DST will end on August 20th. Thanks in advance for any information. Jacquie

Where do you get time zone boundary infomation from ?
by Rod Williams Aug. 7, 2009

Aug. 7, 2009

I am a software engineer working for an avionics company. I am currently working on a project that requires the software I will create to know the time *any place on earth given a latitude and longitude*. Time zone boundaries and time rules will need be *updated on a monthly basis*. This task is proving to be very difficult. The most difficult part is getting up to date data on for time zone boundaries. *Most of the services and databases I have researched only give time zone information for a particular city in that given time zone (ie. Olson Time Zone Database), I have yet to find anything that defines the actual time zone boundaries.* *Is there a service or database that gives up to date boundary and time rules monthly, and has worldwide coverage?* Thanks in advance, Rod Williams

Re: End of DST in Africa/Cairo 2009
by Robin Thorpe Aug. 5, 2009

Aug. 5, 2009

Dear Jacquie, Paul is out of the office on vacation until Monday, August 10, 2009, but I can help you with your question. We are aware of the daylight savings issue in Egypt and are monitoring it closely. According to previous announcements daylight savings time should change the last weekend in September. However, this year is different due to Ramadan starting August 22. It is probable that the government will make a change, but there has been no official decision as of today. Historically the government has made the announcement about one week prior to the start of Ramadan. If they follow this pattern the announcement would come around August 15. According to our sources the last possible day for the announcement is August 20 since Ramadan begins on August 22. We will issue an update as soon as a change is announced and confirmed. I hope this addresses your concerns. If it doesn't or if you have other questions please feel free to email or call me at 212-742-8577. Kind regards, Robin At 02:44 PM 8/5/2009, jacquie(a)entropy.cc wrote: >Hi, > >Does anyone know of an update for the end of DST in Africa/Cairo? >According to the latest tzdata2009k.tar.gz, DST will end on >September 24, 2009.

Will Samoa observe DST?
by Gwillim Law July 30, 2009

July 30, 2009

Last November, the Cabinet of (Western) Samoa approved the adoption of DST from the first Sunday of October 2009 until the last Sunday of March 2010. Alexander Krivenyshev notified the tz list on December 7, with the subject line "Western Samoa may implement Daylight Saving Time in 2009". The tzdata file hasn't reflected any such change yet. I've just done a Web search for any further news. The only relevant articles I could find were dated last November or December. Those articles speak of the change as if it were a done deal; but some of them mention that the Attorney General's office is charged with drafting the enabling legislation. Has Samoa changed its mind and dropped the project? Is the legislation just a formality that's assured of going through? It's a little more than two months until the switch is due. I hope someone on the list is in a position to check into the situation. Gwillim Law

RE: Indiana (East) has no DST set in CLDR supplemental data
by Olson, Arthur David (NIH/NCI) [E] July 27, 2009

July 27, 2009

As Ian Davies observed, CLDR data is supplemental--not part of the time zone package. That being said... "Etc/GMT+5" would have been correct for much of Eastern Indiana through 2006 since DST wasn't observed. (Recall that there's a UNIX-heritage GMT offset sign reversal; use the commands... TZ=Etc/GMT+5 date TZ=EST date TZ=EST5 date ...to see that Etc/GMT+5 used to be the right thing.) Perhaps this particular CLDR data hasn't been updated since 2006. --ado From: Ian Davies [mailto:iand@PartyGaming.com] Sent: Monday, July 27, 2009 5:35 To: Olson, Arthur David (NIH/NCI) [E] Cc: Ian Davies Subject: Indiana (East) has no DST set in CLDR supplemental data Hi, My team has located and fixed an issue in the CLDR supplemental data for Windows TZ mapping. http://unicode.org/cldr/data/common/supplemental/supplementalData.xml Indiana (East) Mapping Changes... 1.

proposed time zone package changes

Here are proposed time zone package changes, with summary information followed by the actual changes. If no problems are found, these will appear on the ftp site in nine days. --ado * zic.c Do not end a binary file with a POSIX-style time zone string for locations that end up in permanent DST (thanks to Andreas Schwab). * asia Arbitrarily cut off Dhaka DST at end of 2009 (so that a POSIX-style time zone string can appear in the Dhaka binary file, and for the benefit of systems with old glibc reimplementations of the time zone library that don't handle permanent DST correctly). Note that another change will be needed once the real end date for DST in Dhaka is known. * africa Change Mauritius to reflect that 2008-2009 DST experiment is not repeated (and to change end of DST in 2009 from 2:00 standard time to 2:00 local time) (thanks to Steffen Thorsen). * europe Update URL for Directive 2000/84/EC on summer-time arrangements (thanks to Colin Watson and Ian Jackson). * leapseconds Change "no leap second" comment (no leap second at end of 2009). * tz-art.htm Add notes on "A Matter of Life and Death" (thanks to Dave Cantor). * tz-link.htm Remove seemingly obsolete public.planetmirror.com/pub/timezone link (thanks to Nathan Stratton Treadway). diff -c old/africa new/africa *** old/africa Sun May 17 14:32:58 2009 --- new/africa Sat Jul 11 12:07:03 2009 *************** *** 1,5 **** # <pre> ! # @(#)africa 8.21 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)africa 8.22 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 502,512 **** # http://www.gov.mu/portal/goc/assemblysite/file/bill2708.pdf # </a> # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Mauritius 1982 only - Oct 10 0:00 1:00 S Rule Mauritius 1983 only - Mar 21 0:00 0 - !

Time zone data for Dhaka is missing an end date
by nikolaus_brauer＠us.ibm.com July 9, 2009

July 9, 2009

To whom it may concern, I am writing to report an issue I have discovered in the recent change to the Asia/Dhaka time zone data, which recently implemented daylight saving time in June. The recent update to the time zone data (tzdata2009j) includes a start date for daylight saving time, but no end date. Intuitively, daylight saving time should have a start and an end date within the same year, otherwise what is implemented is an indefinite GMT offset change. Because of this programs that detect DST rules may see the absence of an end to the DST period as an error. This may cause programs which obtain DST rules using Olson time zone data to fail to detect daylight saving time rules for Asia/Dhaka. For completeness, I propose a tentative end date be implemented now, and an updated date be implemented once an official date is released, or the government releases an additional tentative date in September. According to timeanddate.com: "The press secretary did not confirm the length of DST but stated that the government would decide the DST end date and would announce it later. On another note, Bangladesh's minister for power said earlier in 2009 that the new timing might continue until the end of September. Timeanddate.com will provide an update on the DST end date when it becomes available. " ( http://www.timeanddate.com/news/time/bangladesh-daylight-saving-2009.html ): Timeanddate.com picked September 25th, which seems like a likely enough date. I have update the tzdata on my system with the following rules to implement this change. # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Dhaka09 2009 max - Jun 19 23:00 1:00 D Rule Dhaka09 2009 max - Sep 26 00:00 0:00 S # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Dhaka 6:01:40 - LMT 1890 5:53:20 - HMT 1941 Oct # Howrah Mean Time? 6:30 - BURT 1942 May 15 # Burma Time 5:30 - IST 1942 Sep 6:30 - BURT 1951 Sep 30 6:00 - DACT 1971 Mar 26 # Dacca Time 6:00 Dhaka09 B%sT # Bangladesh Time Could you please evaluate this change for inclusion in the Olson time zone data?

Bangladesh DST end
by ravi-iyer.v＠nokia.com July 7, 2009

July 7, 2009

Hi there, I downloaded tzdata2009j and it does not seem to have the DST end for Bangladesh. I saw couple of threads related to this saying that the end time was still not announced by the Bangladesh government. Is that still the case? Because I can see that timeanddate.com already shows that DST ends on 25th Sep at 12:00am. If this information is correct, when can we expect to see a new version of the database? Regards, Ravi

zic produces wrong POSIX style TZ
by Andreas Schwab June 23, 2009

June 23, 2009

The current Bangladesh time zone description is unusual in that it ends with being continuously in DST. This uncovered a bug in zic, which infers a POSIX TZ string of BDST-6 from the rule. This is wrong since a time zone that is continuously in DST cannot be expressed by POSIX rules, so zic should not try to generate such a string.

I've tried to edit the earlier data file [tzdata2009i.tar.gz] and with little change found following: $zdump -v /etc/localtime | grep 2009 /etc/localtime Fri Jun 19 16:59:59 2009 UTC = Fri Jun 19 22:59:59 2009 BDT isdst=0 gmtoff=21600 /etc/localtime Fri Jun 19 17:00:00 2009 UTC = Sat Jun 20 00:00:00 2009 BDST isdst=1 gmtoff=25200 /etc/localtime Tue Sep 29 16:59:59 2009 UTC = Tue Sep 29 23:59:59 2009 BDST isdst=1 gmtoff=25200 /etc/localtime Tue Sep 29 17:00:00 2009 UTC = Tue Sep 29 23:00:00 2009 BDT isdst=0 gmtoff=21600 #Here is the tzdata/asia file # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Bang 2009 only - Jan 1 0:00 0 - Rule Bang 2009 only - Jun 19 23:00 1:00 S Rule Bang 2009 only - Sep 30 00:00 0 - # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Dhaka 6:01:40 - LMT 1890 5:53:20 - HMT 1941 Oct # Howrah Mean Time? 6:30 - BURT 1942 May 15 # Burma Time 5:30 - IST 1942 Sep 6:30 - BURT 1951 Sep 30 6:00 - DACT 1971 Mar 26 # Dacca Time 6:00 Bang BD%sT But still having problem with backward.

Update URL for 2000/84/EC directive governing current EU DST
by Colin Watson June 18, 2009

June 18, 2009

The 'europe' file in tzdata-2009i has this link: # The most recent directive covers the years starting in 2002. See: # <a href="http://europa.eu.int/eur-lex/en/lif/dat/2000/en_300L0084.html"> # Directive 2000/84/EC of the European Parliament and of the Council # of 19 January 2001 on summer-time arrangements. # </a> The URL given there no longer works properly. Here's an updated one, which Ian Jackson found by way of a search engine: http://eur-lex.europa.eu/smartapi/cgi/sga_doc?smartapi!celexapi!prod!CELEXn… Thanks, -- Colin Watson [cjwatson(a)debian.org]

According to various news reports Bolivia is considering to change Time Zone from GMT-04 to GMT-05 in the winter 2009/2010 to prevent the spread of colds and the new seasonal influenza A strain H1N1. It would be the first time in Bolivian history that changes the time zone.

proposed time zone package change for Bangladesh
by Arthur David Olson June 17, 2009

June 17, 2009

First a note that tzdata2009i.tar.gz does seem to do the expected thing here on the mother system: Script started on Mon Jun 15 06:34:58 2009 lecserver$ ./zdump -v Asia/Dhaka | grep 2009 Asia/Dhaka Fri Jun 19 17:59:59 2009 UTC = Fri Jun 19 23:59:59 2009 BDT isdst=0 Asia/Dhaka Fri Jun 19 18:00:00 2009 UTC = Sat Jun 20 01:00:00 2009 BDST isdst=1 lecserver$ exit script done on Mon Jun 15 06:35:15 2009 However, given this morning's note about DST starting at 23:00... Finally we've got the official mail regarding DST start time where DST start time is mentioned as Jun 19 2009, 23:00 from BTRC (Bangladesh Telecommunication Regulatory Commission). No DST end date has been announced yet. ...and as a way to both simplify the change and avoid glitches, below find a proposed change to the "asia" file. Feedback both on the usefulness of the change and when to push it is welcome. --ado ------- asia ------- *** /tmp/geta26023 Mon Jun 15 06:44:15 2009 --- /tmp/getb26023 Mon Jun 15 06:44:15 2009 *************** *** 1,5 **** # <pre> ! # @(#)asia 8.34 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)asia 8.35 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 165,173 **** # http://www.timeanddate.com/news/time/bangladesh-daylight-saving-2009.html # </a> ! # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S !

Time zone references in art
by Dave Cantor June 16, 2009

June 16, 2009

A possible addition to tz-art.htm : In the 1946 "A Matter of Life and Death", there is a reference to British Double Summer Time. The time does not play a large part in the plot; it's just a passing reference to the time when one of the characters was supposed to have died (but didn't). The IMDb page is at http://us.imdb.com/title/tt0038733/ Dave Cantor Groton, CT
