Now that Steve's message arrived to the list, one more comment:
The quote in question is:

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
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.)
