Sorry for the spam; I swear this is the last message. If I still have it wrong, I'll let someone else straighten it out. :-) In America/Indiana/Knox, on April 2, 2006: 1:59:59 EST is followed by 1:00:00 CST (because this location switches to Central Time at that moment, and it's Standard Time in that zone) 1:59:59 CST is followed by 3:00:00 CDT (the normal DST transition) It doesn't happen in one step; if it went from 1:59:59 to 3:00:00, it would be on EDT, not CDT. If it went from 1:59:59 to 2:00:00, then Knox would be on CDT an hour before the rest of its time zone. Now, that actually makes sense (clocks wouldn't have to change), but it's not what the DOT ruling says. It says "Starke county moves from ET to CT at the moment of the DST transition in the ET zone."
