Mexican time zones in the news.
by Olson, Arthur David (NCI) Jan. 25, 2001

Jan. 25, 2001

The 2001-01-24 traditional Washington Post contained the page one story "Timely Issue Divides Mexicans." An electronic version is available at http://www.washingtonpost.com/wp-dyn/articles/A37383-2001Jan23.html. For this mailing list, the heart of the matter is that Mexico City Mayor Lopez Obrador "...is threatening to keep Mexico City and its 20 million residents on a different time than the rest of the country..." In particular, Obrador would abolish observation of Daylight Saving Time. --ado

RE: New daylight saving period in Mexico
by Jesper Nørgaard Jan. 20, 2001

Jan. 20, 2001

Thanks to Gwillim Law for investigating this matter, and for the pretty accurate translation. I just have a small correction which doesn't change the general outcome. He writes: "In the specific case of Distrito Federal, he telephoned the government of Andrés Manuel López Obrador in order to ascertain his position. [The article doesn't report any conclusion reached in this matter.]" Actually it should be "he urged the government of Andrés Manuel López Obrador to reconsider its position". It is correct that there was no conclusion about that yet. Note that "llamado" here is not a telephone call, but rather a petition, or beckon or attracting attention. Another interesting article was http://www.reforma.com/nacional/articulo/064327/ which in general terms explains the opposition to the daylight saving by various groups in Oaxaca, for instance peasants, teachers and lawyers. But the clou is mentioning the measure the teachers take: "In Oaxaca, the 55.000 teachers from the Section 22 of the National Syndicate of Education Workers, refuse to apply daylight saving each year, so that the more than 10.000 schools work at normal hour the whole year." In other words, all the pupils and teachers of Oaxaca are on Central Standard Time all year round, even when the rest of the state is on Central Daylight Time. Should that be included in the Timezone list? Probably not, but an amusing little revolution it is, similar to the state of affairs in Nunavut at one point, with different offices in the same region having different hour. I have not found an official version of the presidential decree, but I assume that the exact hour that DST is starting and ending is the same as previous years, and indeed the same as for all the USA mainland daylight saving (there are exceptions in american Antarctica stations), e.g. starting at 2:00 Standard time, and ending 2:00 Daylight time.

I found an article at <http://www.reforma.com/negocios_y_dinero/articulo/064481/> that says (translated): Mexico City, January 17, 2000 - The Energy Secretary, Ernesto Martens, announced that Summer Time will be reduced from seven to five months, starting this year. The measure, he said, is in response to the public demand to have one less hour of natural light during the mornings in the first and last month of summer time, in that the latter will begin on the first Sunday in May and will end on the last Sunday of September. This change in the period of application of summer time will entail a reduction of ten weeks in comparison to the original schedule, which envisioned setting the clock an hour ahead from April 1 to October 28. Beginning this year, Mexico will have Summer Time with a duration of 20 weeks. [...] Concerning the possibility that some states in the Republic, including Distrito Federal, may not apply summer time, the official said that in the past, some states decided not to apply the measure, and this caused distortions in relation to the rest of the country. In the specific case of Distrito Federal, he telephoned the government of Andrés Manuel López Obrador in order to ascertain his position. [The article doesn't report any conclusion reached in this matter.] Yours, Gwillim Law

New daylight saving period in Mexico?
by Jesper Nørgaard Welen Jan. 20, 2001

Jan. 20, 2001

According to the following information, we are about to get a decision here in Mexico whether the application of daylight saving will be 2 or 3 months shorter this year or not. The decision is not yet taken, but according to these articles should be taken within 2-3 days: http://www.reforma.com.mx/ciudad_de_mexico/articulo/063682/ http://www.reforma.com.mx/nacional/articulo/063665/ http://www.reforma.com.mx/nacional/articulo/063770/ Regards, Jesper Nørgaard Welen Email: jnorgard(a)Prodigy.Net.mx Programador/Analista CIMMYT - Centro Internacional de Mejoramiento de Maíz y Trigo Dirección: CIMMYT Int. c/o Jesper Nørgaard Km. 45, Carretera México-Veracruz El Batán Texcoco, Edo. de México CP 56130 MEXICO Tel.: +52 (5) 58-04-20-04 ext. 1374 Fax: +52 (5) 58-04-75-58 Tel.

Dear Paul, Here is an addition for the US. Congress just added Guam and the Northern Marianas to the Uniform Time Act and is calling the time zone, "Chomorro standard time" (This is spelled differently in various sources, and I'm not sure of the final correct spelling.) Rives

Right now, "EST" can mean both UTC+10 and UTC+11, as the state of Queensland does not observe daylight-saving time, whereas the other regions in the eastern time zone do (Victoria, Tasmania, and most of New South Wales). And it's not just because "S" stands for "standard" in the former case and "Summer" in the latter: it stands for "standard" in both cases!
