This appears to be a problem in the GNU C library, when its mktime 
deciphers the relatively unusual time zone history of Indiana.

I installed the attached patch into Gnulib and propagated it into 
Coreutils, so the issue should be fixed in the next release of GNU 
Coreutils. Eventually this patch should migrate from Gnulib to glibc so 
that other apps get the fix. Thanks for reporting the issue.
