So it sounds like the actual implementation may not extend all the way down to the Baja/Baja Sur border.
Yes, that sounds definitive. I suppose we could rename America/Santa_Isabel to America/Cedros_Island, since we know Cedros Island observes UTC-8 with Mexican rules. But it'd be nicer if we could find the largest town in that time zone region.
Now that Steve's message arrived to the list, one more comment: The quote in question is:
sometimes after the time change in the US the time zone is different than California, but is not for more than a week, when its similar to Mountain time/ Baja Sur..... I know, what a pain....
This seems a bit less than definitive to me, since during the intervals between the US and Mexican time changes (2nd Sunday in March - first Sunday in April, and last Sunday in in October - first Sunday in November), California (US) and Baja California Sur (Mexico) are at the same UTC offset (UTC-7). It sounds like the author of the quote may be assuming that Baja Sur (Mexico) and California (US) must always be different, and therefore matching one means not matching the other. Two other clarifications to the paragraph at the end of my post yesterday about http://www.cenam.mx/hora_oficial/ndisposicion.aspx . First, there's a link in the sidebar of http://www.cenam.mx/hora_oficial/ to the actual decree at http://dof.gob.mx/nota_detalle.php?codigo=5127480&fecha=06/01/2010 which makes it clear that both paragraphs that I was referring to were from the decree, rather than only the first. Second, there is one bit of ambiguous wording in the decree which is that it always refers to municipalities *except* when referring to Ensenada, when it refers to the *city* of Ensenada. It's not clear to me whether this refers to the municipality or to the capital of that municipality, with the same name. (However, this is not ambiguous in the national government press release that I quoted.) -David -- π L.
