2630 # From Paul Eggert (2006-03-22):


3066 # According to several news sources, Haiti will observe DST this year,
3067 # apparently using the same start and end date as USA/Canada.
3068 # So this means they have already changed their time.

3073 # From Arthur David Olson (2012-03-11):
3074 # The alterpresse.org source seems to show a US-style leap from 2:00 a.m. to
3075 # 3:00 a.m. rather than the traditional Haitian jump at midnight.
3076 # Assume a US-style fall back as well.
3077 
3078 # From Steffen Thorsen (2013-03-10):
3079 # It appears that Haiti is observing DST this year as well, same rules
3080 # as US/Canada.  They did it last year as well, and it looks like they
3081 # are going to observe DST every year now...
