+# From Paul Eggert (1996-02-07):
+# Today in news:4f90v4$g6g@news.internet.com.mx, Kevin Pitts
+# <bravo2@internet.com.mx> wrote that Mexico will use Horario de Verano (DST)
+# starting this year with the same rules as the US, and gave FIDE as a source.
+# (FIDE is a private organization that promotes efficient electrical use.)
+# On 1996-02-02 Mario Camou wrote that the transition times are Apr Sun>=1
+# 0:00 and Nov 1 0:00 but also wrote ``The DST-out date looks a bit fishy''.
+# Go with Pitts after 1996, and with Shanks before that.
