Leap Second Effect on GLOBEX Hours Tonight


[FONT=Calibri]Due to the adjustment of one leap second this evening, Tues, June 30th, GLOBEX will havedelayedopen at 7:45pm Chicago time for all contracts that normally open at 7:00pm or earlier (i.e.; grains, livestock).

Globex contracts that normally open *after *7:45pm will NOT be affected by this delayed opening.

See the CME memo below for additional information. Thank you.

CME Group uses Network Time Protocol (NTP) to synchronize time for CME Globex systems to maintain effective time accuracy. On Tuesday, June 30 (trade date Wednesday, July 1), a positive leap second will be added after 18:59:59 Central Time (CT). A leap second is a one-second adjustment that is added to Coordinated Universal Time (UTC) to account for variability of the earth’s rotation.

To facilitate the Leap Second change and prevent any issues on CME Globex systems, all CME Globex products will have a delayed open at 19:45 CT, 19:30 CT Pre-open, on Tuesday, June 30 (trade date Wednesday, July 1). If a CME Globex product’s regularly scheduled open is post 19:45 CT, then that product will open regularly as scheduled.
