# Before the Uniform Time Act of 1966 took effect in 1967, observance of
# Daylight Saving Time in the US was by local option, except during wartime.
+# From Arthur David Olson (2000-09-25):
+# Last night I heard part of a rebroadcast of a 1945 Arch Oboler radio drama.
+# In the introduction, Oboler spoke of "Eastern Peace Time."
+# An AltaVista search turned up
+# <a href="http://rowayton.org/rhs/hstaug45.html">:
+# "When the time is announced over the radio now, it is 'Eastern Peace
+# Time' instead of the old familiar 'Eastern War Time.' Peace is wonderful."
+# </a> (August 1945) by way of confirmation.
+
+# From Joseph Gallant <notquite@hotmail.com>, citing
+# 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
+# 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.
+
+# From Paul Eggert (2000-10-02):
+# Shanks says that DST was called "War Time" in the US in 1919.
+# In the light of the above, this seems suspect;
+# but we have no better authority yet.
