 # From Paul Eggert (2019-08-28):
+# This quote helps explain the late-1914 situation:
+#   In early November 1914, the Germans imposed the time zone used in central
+#   Europe and forced the inhabitants to set their watches and public clocks
+#   sixty minutes ahead. Many were reluctant to accept "German time" and
+#   continued to use "Belgian time" among themselves. Reflecting the spirit of
+#   resistance that arose in the population, a song made fun of this change....
+# The song ended:
+#   Putting your clock forward
+#   Will but hasten the happy hour
+#   When we kick out the Boches!
