[tz] Fwd: Quintana Roo change to EST?

[Paul Eggert]

There were conflicting reports about this back when Mexico was 
considering doing the change in October of this year.  As I understand 
it, Mexico decided to move the change up to this month, and to stay on 
EST all year.  For a brief summary please see:

It could well be that this is wrong.  There's at least one 
English-language source saying that it hasn't been decided whether 
Quintana Roo will observe DST:

and perhaps we'll need a further update once this becomes decided or 
sufficiently clear.  That being said, my (admittedly limited) 
understanding of QRoo politics suggests that they won't observe DST this 
year.  That CENAM web page is reasonably generic and perhaps its author 
didn't think about (or want to think about) predicting exactly what will 
happen in April.
