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.
A few more links (although Steve Jones's post to which you're replying hasn't made it through to the list yet): A few press releases from early march of this year, from: The mexican national government: http://www.informador.com.mx/mexico/2015/580217/6/horario-de-verano-iniciara... The Baja California state government: http://www.bajacalifornia.gob.mx/portal/noticia_completa.jsp?noticia=25837 And the Ensenada municipal government: http://www.ensenada.gob.mx/xxi/?p=12515 which is of interest since it is the farthest of the 5 municipalities of Baja California from the US border, per: https://en.wikipedia.org/wiki/Municipalities_of_Baja_California The state government press release seems to imply that the entire state follows the US rules. The Ensenada municipality press release lists 11 frontier municipalities in which the US rules apply (including 3 of the 5 municipalities of Baja California), but doesn't imply that the list is complete. It also seems to say the whole state follows US rules. It also says that the Centro Nacional de Metrología is in charge of time in the country. Most interestingly, the national government press release lists 33 municipalities in which the US rules apply (and lists all 5 of the municipalities of Baja California):
Los 33 municipios fronterizos en donde el horario de verano iniciará son: Tijuana, Mexicali, Ensenada, Playa Rosarito y Tecate, en Baja California; Juárez, Ojinaga, Ascensión, Coyame del Sotol, Guadalupe, Janos, Manuel Benavides y Praxedis G. Guerrero, en Chihuahua.
Además de Acuña, Piedras Negras, Guerrero, Hidalgo, Jiménez, Zaragoza, Nava y Ocampo, en Coahuila; Anáhuac y Los Aldama, en Nuevo León; Nuevo Laredo, Reynosa, Matamoros, Camargo, Guerrero, Gustavo Díaz Ordaz, Mier, Miguel Alemán, Río Bravo y Valle Hermoso, en Tamaulipas.
Or, to both translate and present in list form, it's listing the following municipalities in the following states: Baja California (5 of 5 municipalities): Tijuana Mexicali Ensenada Playa Rosarito Tecate Chihuahua (8 of 67 municipalities): Juárez Ojinaga Ascensión Coyame del Sotol Guadalupe Janos Manuel Benavides Praxedis G. Guerrero Coahuila (8 of 38 municipalities): Acuña Piedras Negras Guerrero Hidalgo Jiménez Zaragoza Nava Ocampo Nuevo León (2 of 51 municipalities): Anáhuac Los Aldama Tamaulipas (10 of 43 municipalities): Nuevo Laredo Reynosa Matamoros Camargo Guerrero Gustavo Díaz Ordaz Mier Miguel Alemán Río Bravo Valle Hermoso I got the state totals from: https://en.wikipedia.org/wiki/Municipalities_of_Baja_California https://en.wikipedia.org/wiki/Municipalities_of_Chihuahua https://en.wikipedia.org/wiki/Municipalities_of_Coahuila https://en.wikipedia.org/wiki/Municipalities_of_Nuevo_Le%C3%B3n https://en.wikipedia.org/wiki/Municipalities_of_Tamaulipas The best I could find at the Centro Nacional de Metrología was this: http://www.cenam.mx/hora_oficial/ndisposicion.aspx which first quotes from a decree that lists a smaller list of municipalities, and then gives a broader rule that says all municipalities within 20km of the US border *plus* the municipality of Ensenada in Baja California follow the US rules. (The smaller list quoting from law matches the one in the Ensenada municipalitity's press release with the exception of Ensenada municipality, which is in the municipality's list but not the list in the decree quoted by CENAM.)
