As you may know, the start of Daylight Saving Time (DST) changed this year from the first Sunday in April to the second Sunday in March.  As such, DST begins on March 11, 2007 and continues through the first Sunday in November.   

Clearing schedules will not change; however, the CME would like to remind everyone to ensure that their systems will properly recognize the revised dates of DST in all clearing and message based applications. 

If you have any questions or concerns, please feel free to contact CME Clearing Services at 312.207.2525, or via email at ccs@cme.com.
