+# The [European] Transport Council discussed the proposed Eighth Directive
+# on 11 March and agreed [to] it, so it moves forward to the next stage,
+# from a Commission proposal to a Common Position....  What this means is:
+#
+# - The eighth directive proposal rules have been accepted.
+#   These are the same as the current rules (last Sunday in March and last
+#   Sunday in October).  The rules will run until 2001.
+#
+# - The French have had their request to abandon summer time turned down.
+#   They have been promised some sort of review in 1999 which might change
+#   the rules for 2000 and 2001.
