  42 # From Paul Eggert (1999-03-31):
  43 # Howse writes (pp 121-125) that time zones were invented by
  44 # Professor Charles Ferdinand Dowd (1825-1904),
  45 # Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
  46 # His pamphlet ``A System of National Time for Railroads'' (1870)
  47 # was the result of his proposals at the Convention of Railroad Trunk Lines
  48 # in New York City (1869-10).  His 1870 proposal was based on Washington, DC,
  49 # but in 1872-05 he moved the proposed origin to Greenwich.
  50 # His proposal was adopted by the railroads on 1883-11-18 at 12:00,
  51 # and the most of the country soon followed suit.

1026 # Gwillim Law writes that a good source
1027 # for recent time zone data is the International Air Transport
1028 # Association's Standard Schedules Information Manual (IATA SSIM),
1029 # published semiannually.  Law sent in several helpful summaries
1030 # of the IATA's data after 1990.
1031 #
1032 # Except where otherwise noted, Shanks & Pottenger is the source for
1033 # entries through 1990, and IATA SSIM is the source for entries afterwards.

2659 # From Arthur David Olson (1999-03-29):
2660 # The 1999-03-28 exhibition baseball game held in Havana, Cuba, between
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.
2672 # From Paul Eggert (2006-03-22):
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.

  44 # Professor Charles Ferdinand Dowd (1825-1904),
  45 # Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
  46 # His pamphlet ``A System of National Time for Railroads'' (1870)
  47 # was the result of his proposals at the Convention of Railroad Trunk Lines
  48 # in New York City (1869-10).  His 1870 proposal was based on Washington, DC,
  49 # but in 1872-05 he moved the proposed origin to Greenwich.
  50 # His proposal was adopted by the railroads on 1883-11-18 at 12:00,
  51 # and the most of the country soon followed suit.

2682 # During the game, play-by-play announcer Jim Hunter noted that

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.)
