Subject: Indiana time zones

Actually, there are seven other counties that are moving from Eastern to
Central time. 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.

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:

time, # beginning at the 2006 DST start.
