Since they, like Starke County, do so at the time change, they will simply skip the spring-forward--2:00 EST and 2:00 CDT are identical (both equal 21:00 UTC on the previous day). It appears to me that this requires creating a new zone for the other seven counties, which I show below. # From J. Andrew Lipscomb (2006-01-20): # Department of Transportation ruling http://www.dot.gov/affairs/dot0406.htm # adds eight new counties to the Central (America/Chicago) zone. Six are in # the Evansville area, two near Chicago. One of them (Starke) already has its # own entry; as for the other seven, the largest city in them (and an old # territorial capital) is Vincennes. I suggest that for the exemplar city of # the seven counties. # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone America/Indiana/Vincennes -5:50:04 - LMT 1883 Nov 18 12:09:56 -6:00 US C%sT 1920 -6:00 Indianapolis C%sT 1942 -6:00 US C%sT 1946 -6:00 Indianapolis C%sT 1955 Apr 24 2:00 -5:00 - EST 1957 Sep 29 2:00 -6:00 - CST 1958 Apr 27 2:00 -5:00 - EST 1969 -5:00 US E%sT 1971 -5:00 - EST 2006 Apr 2 2:00 -6:00 US C%sT In addition to the section above, the new zone will need to be added to the zone.tab file. Vincennes' location is +384042-0873058. And to cover Starke County: # From J.
