+# American journalist John Seigenthaler, who was there:
+#
+# "The two [newspaper] owners held strongly contrasting political and
+# ideological views.  Evans was a New South liberal, Stahlman an Old South
+# conservative, and their two papers frequently clashed editorially, often on
+# the same day....  In the 1950s as the state legislature was grappling with
+# the question of whether to approve daylight saving time for the entire state,
+# TIME magazine reported:
+#
+# "'The Nashville Banner and The Nashville Tennessean rarely agree on anything
+# but the time of day - and last week they couldn't agree on that.'
+#
+# "It was all too true. The clock on the front of the building had two faces -
+# The Tennessean side of the building facing west, the other, east.  When it
+# was high noon Banner time, it was 11 a.m. Tennessean time."

-# the last fly ball of the doubleheader settled into the glove of leftfielder

-# https://www.freep.com/story/sports/mlb/tigers/2017/07/23/detroit-tigers-1967-riot-new-york-yankees/499951001/
+# From Paul Eggert (2019-07-06):
+# Due to a complicated set of legal maneuvers, in 1967 Michigan did
+# not start daylight saving time when the rest of the US did.
+# Instead, it began DST on Jun 14 at 00:01.  This was big news:
+# the Detroit Free Press reported it at the top of Page 1 on
+# 1967-06-14, in an article "State Adjusting to Switch to Fast Time"
+# by Gary Blonston, above an article about Thurgood Marshall's
+# confirmation to the US Supreme Court.  Although Shanks says Detroit
+# observed DST until 1967-10-29 00:01, that time of day seems to be
+# incorrect, as the Free Press later said DST ended in Michigan at the
+# same time as the rest of the US.  Also, although Shanks reports no DST in
+# Detroit in 1968, it did observe DST that year; in the November 1968
+# election Michigan voters narrowly repealed DST, effective 1969.

+# Pearce's book says that Alberta's 1948 Daylight Saving Act required
+# Mountain Standard Time without DST, and that "anyone who broke that law
