Looks like we re-open an hour earlier now. "As previously announced, the CBOT will implement a 22 hour trading day on its electronic platform. The expansion of trading hours is in response to global demand for additional trading opportunities at the Exchange. This enhancement will be completed in conjunction with the upgrade to Release 9.0 on the CBOT electronic platform on October 9, 2005, and will make CBOT products available to electronic market users for one additional hour each day." http://www.cbot.com/cbot/pub/page/0,3181,932,00.html#interestrate
