+# I came across another article in "La Tercera" about Chilean DST.
+# <http://www.tercera.cl/diario/2000/10/13/t-extras.html>
+# It clearly confirms my earlier suggestion, that DST begins at 22:00
+# on Easter Island.... But it also seems to be saying that the
+# observance of DST in Chile began in 1966, rather than 1969 as
+# ... [Shanks] has it....
+#
+# My translation:
+#
+# "The Chilean Army has announced that summer time will begin tomorrow,
+# Saturday, October 14 in continental Chile, insular Chile, and
+# Antarctica, as provided by Supreme Decree 25 of January 11, 1966.
+# By the preceding, official time in continental Chile and Chilean
+# Antarctic, and official time in Western Insular Chile, which applies
+# to Easter Island and Sala y Gomez Island, will be set forward at
+# midnight and at 22:00, respectively, by 20 minutes."
+
+# From Paul Eggert (2001-05-04):
+# Go with this article in preference to Shanks's 1969 date for modern DST.
# Assume this rule has been used since DST was introduced in the islands.
