+# Howse writes (pp 121-125) that time zones were invented by
+# Professor Charles Ferdinand Dowd (1825-1904),
+# Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
+# His pamphlet ``A System of National Time for Railroads'' (1870)
+# was the result of his proposals at the Convention of Railroad Trunk Lines
+# in New York City (1869-10).  His 1870 proposal was based on Washington, DC,
+# but in 1872-05 he moved the proposed origin to Greenwich.
+# His proposal was adopted by the railroads on 1883-11-18 at 12:00,
+# and the most of the country soon followed suit.
