Possible changes for DST in Haiti are attached; for convenience they also
appear below (with tabs mangled by Gmail).
(This is a case where even though right now the Rules cover just one year
we're motiviated to use stuff such as "Sun>=8"
to ease extension of the rules if appropriate in 2013.)

# From Stephen Colebourne (2007-02-22):
# Some IATA info: Haiti won't be having DST in 2007.
+ # From Steffen Thorsen (2012-03-11):
+ # According to several news sources, Haiti will observe DST this year,
+ # apparently using the same start and end date as USA/Canada.
+ # So this means they have already changed their time.

to
