-# </a> (1999-04-06)

+#
+# From Paul Eggert (2005-08-22):
+# Since 1970, most of Indiana has been like America/Indiana/Indianapolis,
+# with the following exceptions:
+#
+# - Gibson, Jasper, Lake, LaPorte, Newton, Porter, Posey, Spencer,
+#   Vandenburgh, and Warrick counties have been like America/Chicago.
+#
+# - Dearborn and Ohio counties have been like America/New_York.
+#
+# - Clark, Floyd, and Harrison counties have been like
+#   America/Kentucky/Louisville.
+#
+# - Crawford, Starke, and Switzerland counties have their own time zone
+#   histories as noted below.
 #
-# From Paul Eggert (1995-12-19):
-# Indiana generally observes either EST all year, or CST/CDT,
-# but areas near Cincinnati and Louisville use those cities' timekeeping
-# and in 1969 and 1970 the whole state observed daylight time;
-# and there are other exceptions as noted below.
 # Shanks partitions Indiana into 345 regions, each with its own time history,
 # and writes ``Even newspaper reports present contradictory information.''
 # Fortunately, most of the complexity occurred before our cutoff date of 1970.
 #
-# Since 1970, EST-only Indiana has been like America/Indianapolis,
-# with exceptions noted below for Crawford, Starke, and Switzerland counties.
-# The parts of Indiana not listed below have been like America/Chicago,
-# America/Louisville, or America/New_York.
-#
 # Other than Indianapolis, the Indiana place names are so nondescript
 # that they would be ambiguous if we left them at the `America' level.
 # So we reluctantly put them all in a subdirectory `America/Indiana'.
-#
-# Most of EST-only Indiana last observed DST in 1970.
 
-# From Paul Eggert (2001-03-06), following a tip by Markus Kuhn:
-# Pam Belluck reported in the New York Times (2001-01-31) that the
-# Indiana Legislature is considering a bill to adopt DST statewide.
-# Her article mentioned Vevay, whose post office observes a different
-# time zone from Danner's Hardware across the street.
