various time changes
by Rives McDow Dec. 5, 2000

Dec. 5, 2000

Dear Paul, Here are some changes in time zones that have come to my attention recently. Tonga is observing DST as of November 4, 2000, and will stop on January 27, 2001. Dominican Republic changed it's mind and presidential decree on Tuesday, November 28, 2000, with a new decree. On Sunday, December 3 at 1:00 AM the Dominican Republic will be reverting to 8 hours from the International Date Line, and will not be using DST in the foreseeable future. The reason they decided to use DST was to be in synch with Puerto Rico, who was also going to implement DST. When Puerto Rico didn't implement DST, the president decided to revert. Jordan will most probably implement DST next March (2001), on the last Thursday. However, with them, it is not possible to predict this with any certainty. If they do implement it, it will run to the last Thursday of September, 2001. Rives McDow

Fiji and Tonga has stopped using DST
by Steffen Thorsen Dec. 5, 2000

Dec. 5, 2000

Risto Nykänen <ristonykanen(a)luukku.com> has reported to me that both Tonga and Fiji has stopped using DST. I have tried to research this a little bit further, and found an official statement about Fiji: from http://www.fiji.gov.fj/core/press/2000_09_26_4.html > The interim government has decided not to introduce "daylight saving" > this year. > > A spokesman for the Ministry of Labour said the decision follows > strong opposition from some commercial enterprises and the Ministry of > Education who were concerned about the disruptions caused to school > children, especially during the examination periods. > This means that as from Sunday 4th, November, there will be no change > as normal standard time will keep on operating. I have not found anything for Tonga, but it is actually no surprise if they have stopped using DST, as the "first into year 2000" hype has ended. Back in March I found a notice on the website http://www.tongaonline.com that Tonga changed back to standard time one month early, on March 19 instead of the original reported date April 16. Unfortunately, the article is no longer available on the site, and I did not make a copy of the text, and I have forgotten to report it here.

TZ and DST changes for East Timor and Dominican Republic
by Steffen Thorsen Dec. 5, 2000

Dec. 5, 2000

* East Timor seems to have changed time zone from GMT+8 to GMT+9, around the end of September. * The Dominican Republic is now using the same time zone as Eastern US with DST during summer (EST/EDT). detail information: East Timor: Charles C. Schlegel" <chucks(a)bkk3.loxinfo.co.th> reported this: > I have just returned from East Timor, and have discovered that the UN > Transitional Authority there has decided to change the time zone of > the country. I think it took effect at the end of September. E. > Timor time is now 2 hours ahead of Bangkok, not one hour as before. > > I don't know just who you could contact to get formal confirmation of > this. The political/administrative structure in E. Timor is still > very much in a state of evolution. The legal governing body at > present is = the UN Transitional Authority for East Timor (UNTAET). Dominican Republic: Enrique Morales <emorales(a)pnud.org.do> reported to me that the Dominican Republic has changed the time zone to Eastern Standard Time as of Sunday 29 at 2 am. Some sort of "official" statement is available in Spanish here: http://www.listin.com.do/antes/261000/republica/princi.html Use of http://babelfish.altavista.com to "translate" to English: > Power Executive modified last night decree previous which the next > Sunday 29 arranged to retard in one hour the clocks in all the country > to 12:00 of the midnight, that now will be the same day but to 2:00 of > the dawn, to avoid probable disadvantages in the services of > telecommunications. > > Decree 1011, emitted last night, arranges that > the delay is from the 2:00 of the dawn of the same Sunday 29, instead > of the 12:00 of the midnight of that same day, as it established the > previous one, the 820-00, of the 25 of last September. The new decree > arranges in addition that the Sunday first of April of next year 2001, > to 2:00 of the dawn, all the clocks are advanced in one hour. [continues ...] I have some other tz updates to report as well, I hope to have them ready tomorrow.

RE: Brazil again
by Jesper Nørgaard Dec. 4, 2000

Dec. 4, 2000

The recent changes to abandon DST in the states Pernambuco and Roraima as of October 15, and Alagoas, Sergipe, Paraíba, Rio Grande do Norte, Ceará, Piauí and Maranhão as of October 21, will surely make necessary to invent new time zone items in the TZ database. But I suggest two more changes that are not directly generated from these events. I checked out the pages mentioned by Steffen Thorsen http://pcdsh01.on.br/DecHV.html and found a couple of pages that should be of interest Brazil on Standard Time: http://pcdsh01.on.br/Fusbr.htm Brazil on Daylight Time: http://pcdsh01.on.br/Fusbrhv.htm Unfortunately these two pages have not been updated as per the last changes from 15.th. and 21.st October 2000, but they reflect well how the situation was supposed to be before those dates. NEW TIMEZONE IN AMAZONAS Since the TZ database for Brazil has been elaborated per state, we have an obligation to document the exceptions from that. In the case of Amazonas we only have one entry "America/Manaus" on GMT-4.0 without DST, but according to the pages there is a region of the Amazonas State with GMT-5.0 without DST (like Acre or the "America/Porto_Acre" entry). The city information I have about this follows here: GMT-4.0 without DST @ Brazil - Amazonas East, Manaus,-3.10,-60.00 Borba,-4.39,-59.59 Coarí,-4.11,-63.14 Fonte Boa,-2.53,-66.02 Humaitá,-7.52,-63.02 Lábrea,-7.27,-64.78 Moura,-4.12,-63.42 Bôca do Acre,-8.75,-67.38 Jutaí,-5.18,-68.90 Floriano Peixoto,-9.07,-67.42 GMT-5.0 without DST @ Brazil - Amazonas West, Atalaia do Norte,-4.33,-70.20 Benjamin Constant,-4.37,-70.03 Eirunepé,-6.67,-69.87 Envira,-7.30,-70.22 Ipixuna,-7.57,-72.60 The format is {@ Country/State} City, Latitude, Longitude Therefore I suggest to put a second entry in the TZ database for Amazonas as "America/Atalaia_do_Norte" or something like that. FERNANDO DO NORONHA ON DST According to these official pages, Fernando do Noronha has been on DST for some while back (e.g. before October 15 where the status probably changed). This is as a contrast to other islands like Trindade and Martin Vaz, which have not been on DST according to the pages. This change to the status of Fernando do Noronha could well be linked with the change of status of the islands from being "self ruling" to be under the rule of state Pernambuco. I don't have information when these events should have happened, but the issue is worthwhile investigating. The ironic thing is that at this point when I'm reporting that Fernando do Noronha has been on DST, it most probably is no longer on DST. This is because it now is under Pernambuco State rule, and since Pernambuco abandoned DST on October 15, probably the island did the same. By the way the TZ database is mentioning Fernando do Noronha as "Fernando de Noronha". I believe it should be spelled with "do" instead of "de".

Now looking at the official page http://pcdsh01.on.br/DecHV.html : It seems that Pernambuco and Roraima stopped using DST on 15 October at midnight. Then, just one week later, Sergipe, Alagoas, Paraiba, Rio Grande do Norte, Ceará, Piauí and Maranhão stopped using DST on 22 October at midnight.

Re: NTP and POSIX Time in conflict?
by Bradley White Dec. 4, 2000

Dec. 4, 2000

> 1. I have heard it claimed that the broken-ness of posix time > prevented NTP from handling leap seconds correctly. Would you care > to comment on this? Specifically, what specific brokenness causes > what problem? POSIX legislates a particular mapping between time_t's and the time of day (e.g., 536457599 shall correspond to "Wed Dec 31 23:59:59 UTC 1986"). So, POSIX time must be adjusted over leap seconds. The premier NTP implementation goes to convoluted lengths to perform that adjustment. The "correct" way to handle leap seconds is a matter of opinion, but `ado-right' stalwarts would contend that using a continuous time base results in a better system, and treating time_t as opaque gets you there. See time2posix(3) in the ado source for more details. Bradley

RE: Asia/Dacca Spelling
by Olson, Arthur David (NCI) Dec. 4, 2000

Dec. 4, 2000

> The following was reported by Steve Minkin regarding the current time zone > Asia/Dacca. Please note that Steve is not on this distribution list. Should > the spelling for this time zone be changed? Should an alias be defined? > "Please note that about 10 years ago the spelling of the capital of > bangladesh changed from Dacca to Dhaka. No one uses Dacca any more." A search at www.un.org yields 30 hits on Dhaka and one on Dacca. The page http://www.xrefer.com/entry/501998, attributed to "The Macmillan Encyclopedia 2001, © Market House Books Ltd 2000," contains: "Dhaka (name until 1982: Dacca)." So...my sense is that the thing to change "Zone Asia/Dacca" to "Zone Asia/Dhaka" and add a "Link Asia/Dhaka Asia/Dacca" to the "backward" file. --ado

Some older Summer Time Orders now online
by Joseph S. Myers Dec. 3, 2000

Dec. 3, 2000

Some British Government web sites have lately been getting older publications online (mainly so far, I think, data they already had in electronic form but was only available if at all on expensive CD-ROMs or subscription databases) - including Acts back to 1988, Statutory Instruments back to 1987 and Hansard back to 1988. Accordingly, my web page now links to the Summer Time Orders 1988, 1989, 1992 and 1994. http://student.cusu.cam.ac.uk/~jsm28/british-time/ -- Joseph S. Myers jsm28(a)cam.ac.uk

Rumours about DST changes in Mexico
by Jesper Nørgaard Dec. 3, 2000

Dec. 3, 2000

I found an article that is 1 month old, about a daylight saving change in Mexico which Vicente Fox apparently has suggested before he came to power. No changes have been implemented yet, but the new elected president Vicente Fox seems to agree with his presidential candidate opponent Labastida that daylight saving should not be discontinued, but maybe reduced with a couple of months, e.g. starting one month later and ending one month earlier: http://www.reforma.com/nacional/articulo/044581/ unfortunately the article is in spanish, but it doesn't say much more than what I was referring, at least of interest to this mailing list. The article is from 29.th. of October, e.g. right after leaving daylight saving in Mexico. Details about implementation are not there, and I'm pretty sure the decision has not been taken yet. Vicente Fox just became acting president this Friday December 1, 2000. I wonder if they have taken into consideration the disadvantages of having 2 months of the year a different hour than similar zones in USA, the main receiver of exports from Mexico.

RE: Nunavut (northern Canada) changes time zones again
by Jesper Nørgaard Nov. 30, 2000

Nov. 30, 2000

There was news about the Nunavut time zones in Nuniatsaq News the 10.th. of November, but I didn't see it until today. The link is http://www.nunatsiag.com/archives/nunavut001130/nvt21110_02.html although this seems to be a dynamic address with date and time; Check out the Nunatsiaq News archives from 10.th of November to find the article, if the above doesn't work. Quote: "After a week of confusion, clocks in the territory's westernmost hamlets are now synchronized - an hour behind the rest of Nunavut. The Nunavut government last week retreated from its unified-time-zone policy, permitting Kugluktuk and Cambridge Bay to stay on central time for the winter. ... Anawak said the Nunavut government would allow its employees in Kugluktuk and Cambridge Bay to operate on central time year-round, putting them one hour behind the rest of Nunavut for six months during the winter." The only way I can get this to match, is if Kugluktuk and Cambridge Bay will be on Central Time all year round (e.g. GMT-6 with DST) while the rest of the central and eastern Nunavut will be on Eastern Standard Time all year round (e.g. GMT-5 without DST), so that during winter Kugluktuk will be one hour behind, and in the summer will be on the same time as the rest of Nunavut. This implicitly means that Central and Eastern Nunavut does *not* have daylight saving. I wonder if any of you have any comments on this, or more official documentation. The above article seems to go to great lengths to express daylight saving issues without mentioning the (forbidden?) term "daylight saving". Perhaps it has become too political in Nunavut to imply that you can gain something with "daylight saving" ;) ? Can the article be interpreted any other way?

The territory originally straddled three zones, and efforts to impose a single time for all of Nunavut have met with vocal opposition. The latest change (effective Mon. 2000-11-06) appears to keep most of the territory on UTC-5h (i.e., CDT in summer and EST in winter) year- round. However, some communities in western Nunavut will set their clocks an hour earlier, to UTC-6h. The news story didn't make it clear whether western Nunavut would change its clocks in the summer or not. Also, the National Research Council -- Canada's federal regulatory body for time zones -- hasn't updated its maps yet (http://www.nrc.ca/inms/time/tze.html) to reflect the latest change in Nunavut.
