2661 # the Cuban National Team and the Baltimore Orioles was carried live on
2662 # the Orioles Radio Network, including affiliate WTOP in Washington, DC.
2663 # During the game, play-by-play announcer Jim Hunter noted that
2664 # "We'll be losing two hours of sleep...Cuba switched to Daylight Saving
2665 # Time today." (The "two hour" remark referred to losing one hour of
2666 # sleep on 1999-03-28--when the announcers were in Cuba as it switched
2667 # to DST--and one more hour on 1999-04-04--when the announcers will have
2668 # returned to Baltimore, which switches on that date.)
2669
2670 # From Evert van der Veer via Steffen Thorsen (2004-10-28):
2671 # Cuba is not going back to standard time this year.

2673 # http://www.granma.cu/ingles/2004/septiembre/juev30/41medid-i.html
2674 # says that it's due to a problem at the Antonio Guiteras
2675 # thermoelectric plant, and says "This October there will be no return
2676 # to normal hours (after daylight saving time)".
2677 # For now, let's assume that it's a temporary measure.
2678
2987 #
2988 # From Steffen Thorsen (2006-04-04):
2989 # I have been informed by users that Haiti observes DST this year like
2990 # last year, so the current "only" rule for 2005 might be changed to a
2991 # "max" rule or to last until 2006. (Who knows if they will observe DST
2992 # next year or if they will extend their DST like US/Canada next year).
2993 #
2994 # I have found this article about it (in French):
2995 # http://www.haitipressnetwork.com/news.cfm?articleID=7612
2996 #
2997 # The reason seems to be an energy crisis.
2998
2999 # From Stephen Colebourne (2007-02-22):
3000 # Some IATA info: Haiti won't be having DST in 2007.
3001
3002 # From Steffen Thorsen (2012-03-11):
3003 # According to several news sources, Haiti will observe DST this year,
3004 # apparently using the same start and end date as USA/Canada.
3005 # So this means they have already changed their time.

2677
2678 # From Arthur David Olson (1999-03-29):
2679 # The 1999-03-28 exhibition baseball game held in Havana, Cuba, between
2680 # the Cuban National Team and the Baltimore Orioles was carried live on
2681 # the Orioles Radio Network, including affiliate WTOP in Washington, DC.
2682 # During the game, play-by-play announcer Jim Hunter noted that
2683 # "We'll be losing two hours of sleep...Cuba switched to Daylight Saving
2684 # Time today." (The "two hour" remark referred to losing one hour of
2685 # sleep on 1999-03-28--when the announcers were in Cuba as it switched
2686 # to DST--and one more hour on 1999-04-04--when the announcers will have
2687 # returned to Baltimore, which switches on that date.)
2688
2689 # From Evert van der Veer via Steffen Thorsen (2004-10-28):
2690 # Cuba is not going back to standard time this year.
2691 # From Paul Eggert (2006-03-22):
2692 # http://www.granma.cu/ingles/2004/septiembre/juev30/41medid-i.html
2693 # says that it's due to a problem at the Antonio Guiteras
2694 # thermoelectric plant, and says "This October there will be no return
2695 # to normal hours (after daylight saving time)".
2696 # For now, let's assume that it's a temporary measure.
2697
3006 #
3007 # From Steffen Thorsen (2006-04-04):
3008 # I have been informed by users that Haiti observes DST this year like
3009 # last year, so the current "only" rule for 2005 might be changed to a
3010 # "max" rule or to last until 2006. (Who knows if they will observe DST
3011 # next year or if they will extend their DST like US/Canada next year).
3012 #
3013 # I have found this article about it (in French):
3014 # http://www.haitipressnetwork.com/news.cfm?articleID=7612
3015 #
3016 # The reason seems to be an energy crisis.
3017
3018 # From Stephen Colebourne (2007-02-22):
3019 # Some IATA info: Haiti won't be having DST in 2007.
3020
3021 # From Steffen Thorsen (2012-03-11):
3022 # According to several news sources, Haiti will observe DST this year,
3023 # apparently using the same start and end date as USA/Canada.
3024 # So this means they have already changed their time.

3029 # From Arthur David Olson (2012-03-11):
3030 # The alterpresse.org source seems to show a US-style leap from 2:00 a.m. to
3031 # 3:00 a.m. rather than the traditional Haitian jump at midnight.
3032 # Assume a US-style fall back as well.
3033
3034 # From Steffen Thorsen (2013-03-10):
3035 # It appears that Haiti is observing DST this year as well, same rules
3036 # as US/Canada. They did it last year as well, and it looks like they
3037 # are going to observe DST every year now...
