# George H. Douglas, _The Early Days of Radio Broadcasting_ (1987):
# At 7 P.M. (Eastern War Time) [on 1945-08-14], the networks were set
-# to switch to London for Atlee's address, but the American people
+# to switch to London for Attlee's address, but the American people
# never got to hear his speech live. According to one press account,
# CBS' Bob Trout was first to announce the word of Japan's surrender,
# but a few seconds later, NBC, ABC and Mutual also flashed the word
# of surrender, all of whom interrupting the bells of Big Ben in
-# London which were to precede Mr. Atlee's speech.
+# London which were to precede Mr. Attlee's speech.
+
+# From Paul Eggert (2003-02-09): It was Robert St John, not Bob Trout. From
+# Myrna Oliver's obituary of St John on page B16 of today's Los Angeles Times:
+#
+# ... a war-weary U.S. clung to radios, awaiting word of Japan's surrender.
+# Any announcement from Asia would reach St. John's New York newsroom on a
+# wire service teletype machine, which had prescribed signals for major news.
+# Associated Press, for example, would ring five bells before spewing out
+# typed copy of an important story, and 10 bells for news "of transcendental
+# importance."
+#
+# On Aug. 14, stalling while talking steadily into the NBC networks' open
+# microphone, St. John heard five bells and waited only to hear a sixth bell,
+# before announcing confidently: "Ladies and gentlemen, World War II is over.
+# The Japanese have agreed to our surrender terms."
+#
+# He had scored a 20-second scoop on other broadcasters.

# Howse writes that Alaska switched from the Julian to the Gregorian calendar,

+# time, but by federal law railroads, airlines, bus lines, military
+# personnel, and some engaged in interstate commerce continued to

+# Gazette says that was the date the law changed, and that 04-01 was
+# the date the state's clocks would change. In 1945 the State of
+# Arizona used standard time all year, again with exceptions only as
+# mandated by federal law. Arizona observed DST in 1967, but Arizona
+# Laws 1968, ch. 183 (effective 1968-03-21) repealed DST.
