Proposed changes for Cuba, Iraq, and San Luis, Argentina

Sat Mar 15 18:02:38 UTC 2008


Here are proposed changes to files in the time zone distribution;
these are relative to tzdata2008a.tar.gz. Changes are made to:
	asia: Iraq abandons DST
	northamerica: Cuba changes start of DST
	southamerica and zone.tab: San Luis, Argentina goes to UTC-3 year-round
Absent feedback, I plan to make tzdata2008b.tar.gz available March 24, 2008
(about a week before the Iraq change affects current time stamps).
Note: we still don't have good information about historic practice in San Luis.

+ # From Arthur David Olson (2008-03-09):
+ # I'm in Maryland which is now observing United States Eastern Daylight
+ # Time. At 9:44 local time I used RealPlayer to listen to
+ # <a href="http://media.enet.cu/radioreloj">
+ # http://media.enet.cu/radioreloj
+ # </a>, a Cuban information station, and heard
+ # the time announced as "ocho cuarenta y cuatro" ("eight forty-four"),
+ # indicating that Cuba is still on standard time.
+ 
+ # From Steffen Thorsen (2008-03-12):
+ # It seems that Cuba will start DST on Sunday, 2007-03-16...
+ # It was announced yesterday, according to this source (in Spanish):
+ # <a href="http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm">
+ # http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm
+ # </a>
+ #
+ # Some more background information is posted here:
+ # <a href="http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html">
+ # http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html
+ # </a>
+ #
+ # The article also says that Cuba has been observing DST since 1963,
+ # while Shanks (and tzdata) has 1965 as the first date (except in the
+ # 1940's). Many other web pages in Cuba also claim that it has been
+ # observed since 1963, but with the exception of 1970 - an exception
+ # which is not present in tzdata/Shanks. So there is a chance we need to
+ # change some historic records as well.
+ #
+ # One example:

+ # http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm
+ # </a>
+ 
+ # From Jesper Norgaard Welen (2008-03-13):
+ # The Cuban time change has just been confirmed on the most authoritative
+ # web site, the Granma.  Please check out
+ # <a href="http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html">
+ # http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html
+ # </a>
+ #
+ # Basically as expected after Steffen Thorsens information, the change
+ # will take place midnight between Saturday and Sunday.
+ 
+ # From Arthur David Olson (2008-03-12):
+ # Assume Sun>=15 (third Sunday) going forward.

+ # From Alex Krivenyshev (2008-01-17):
+ # Here are articles that Argentina Province San Luis is planning to end DST
+ # as earlier as upcoming Monday January 21, 2008 or February 2008:
+ #
+ # Provincia argentina retrasa reloj y marca diferencia con resto del pais
+ # (Argentine Province delayed clock and mark difference with the rest of the

+ # From Jesper Norgaard Welen (2008-01-18):
+ # The page of the San Luis provincial government
+ # <a href="http://www.sanluis.gov.ar/notas.asp?idCanal=0&id=22812">
+ # http://www.sanluis.gov.ar/notas.asp?idCanal=0&id=22812
+ # </a>
+ # confirms what Alex Krivenyshev has earlier sent to the tz
+ # emailing list about that San Luis plans to return to standard
+ # time much earlier than the rest of the country. It also
+ # confirms that upon request the provinces San Juan and Mendoza 
+ # refused to follow San Luis in this change. 
+ # 
+ # The change is supposed to take place Monday the 21.st at 0:00
+ # hours. As far as I understand it if this goes ahead, we need
+ # a new timezone for San Luis (although there are also documented
+ # independent changes in the southamerica file of San Luis in
+ # 1990 and 1991 which has not been confirmed).
+ 
+ # From Jesper Norgaard Welen (2008-01-25):
+ # Unfortunately the below page has become defunct, about the San Luis
+ # time change. Perhaps because it now is part of a group of pages "Most
+ # important pages of 2008."
+ #
+ # You can use
+ # <a href="http://www.sanluis.gov.ar/notas.asp?idCanal=8141&id=22834">
+ # http://www.sanluis.gov.ar/notas.asp?idCanal=8141&id=22834
+ # </a>
+ # instead it seems. Or use "Buscador" from the main page of the San Luis
+ # government, and fill in "huso" and click OK, and you will get 3 pages
+ # from which the first one is identical to the above.
+ 
+ # From Mariano Absatz (2008-01-28):
+ # I can confirm that the Province of San Luis (and so far only that
+ # province) decided to go back to UTC-3 effective midnight Jan 20th 2008
+ # (that is, Monday 21st at 0:00 is the time the clocks were delayed back
+ # 1 hour), and they intend to keep UTC-3 as their timezone all year round
+ # (that is, unless they change their mind any minute now).
+ #
+ # So we'll have to add yet another city to 'southamerica' (I think San
+ # Luis city is the mos populated city in the Province, so it'd be
+ # America/Argentina/San_Luis... of course I can't remember if San Luis's
+ # history of particular changes goes along with Mendoza or San Juan :-(
+ # (I only remember not being able to collect hard facts about San Luis
+ # back in 2004, when these provinces changed to UTC-4 for a few days, I
+ # mailed them personally and never got an answer).
+ 
+ # From Arthur David Olson (2008-03-15):
+ # Until there's better information, asssume San Luis was like San Juan
+ # rather than Mendoza (since San Juan has a simpler DST history).
+ 
  # Unless otherwise specified, data are from Shanks & Pottenger through 1992,
  # from the IATA otherwise.  As noted below, Shanks & Pottenger say that
  # America/Cordoba split into 6 subregions during 1991/1992, but we
