As part of the Energy Policy Act signed in 2005 by President George W. Bush, the U.S. Daylight Saving Time (DST) schedule has been revised.  This change will extend DST by a total of one month, starting three weeks earlier on the second Sunday in March and ending one week later on the first Sunday in November.  DST saves energy by lowering the demand for electricity during the hours consumers are awake.

In order to prepare for the March 11, 2007 change, the CBOT has evaluated all hardware and associated applications for potentially altered time stamps, clocks, or otherwise affected functionality.  All technical teams are involved in addressing any necessary changes as well as verification testing of environments post DST modifications. 

System changes have been underway and will continue through February 25, 2007.  These changes will not hinder the normal day to day business processes.

In summary the CBOT is prepared for the DST change. Please contact me if you have further questions or concerns.

Sincerely,

Steve Dickey
