But my proposed rules do that.  "zdump -v America/Indiana/Knox"
outputs this for me:

   ...
   America/Indiana/Knox  Sun Apr  2 06:59:59 2006 UTC = Sun Apr  2 01:59:59 2006 EST isdst=0
   America/Indiana/Knox  Sun Apr  2 07:00:00 2006 UTC = Sun Apr  2 02:00:00 2006 CDT isdst=1
   ...

Are you getting different output from zdump?

I vaguely recall that zic used to have problems in this area.  Perhaps
your zic is old and has the bug?  If so, I suppose we should alter the
data files to work around those old zic bugs.

I'll send email to Judith Kaleta of the DOT about the screwup in their
regulations, and CC: to this list.
