+# From Arthur David Olson (2008-03-09):
+# I'm in Maryland which is now observing United States Eastern Daylight
+# Time. At 9:44 local time I used RealPlayer to listen to
+# <a href="http://media.enet.cu/radioreloj">
+# http://media.enet.cu/radioreloj
+# </a>, a Cuban information station, and heard
+# the time announced as "ocho cuarenta y cuatro" ("eight forty-four"),
+# indicating that Cuba is still on standard time.
+
+# From Steffen Thorsen (2008-03-12):
+# It seems that Cuba will start DST on Sunday, 2007-03-16...
+# It was announced yesterday, according to this source (in Spanish):
+# <a href="http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm">
+# http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm
+# </a>
+#
+# Some more background information is posted here:
+# <a href="http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html">
+# http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html
+# </a>
+#
+# The article also says that Cuba has been observing DST since 1963,
+# while Shanks (and tzdata) has 1965 as the first date (except in the
+# 1940's). Many other web pages in Cuba also claim that it has been
+# observed since 1963, but with the exception of 1970 - an exception
+# which is not present in tzdata/Shanks. So there is a chance we need to
+# change some historic records as well.
+#
+# One example:
+# <a href="http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm">
+# http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm
+# </a>
+
+# From Jesper Norgaard Welen (2008-03-13):
+# The Cuban time change has just been confirmed on the most authoritative
+# web site, the Granma.  Please check out
+# <a href="http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html">
+# http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html
+# </a>
+#
+# Basically as expected after Steffen Thorsens information, the change
+# will take place midnight between Saturday and Sunday.
+
+# From Arthur David Olson (2008-03-12):
+# Assume Sun>=15 (third Sunday) going forward.
