Many years ago, a user filed a bug report that the timezone information we used for historical places in Indiana was incorrect. I don't remember exactly what the user was doing, but I think it had something to do with train schedules or something.

I did not fix that bug. (But I did learn that the 'TZ' database has this information, though I think 'America/Indiana/*' had been pruned out of the copy our JVM was using.)
