trading hours start on 10/27/14 and I think they go from 8:00 A.M. CST TO 5:00 P.M. EST. I'm quite sure the closing time is correct. I may be off by one hour on the opening time.
There was some discussion about adding Jan, Mar, Sept and Nov contracts but I guess that idea got left on the drawing board. Perhaps they thought not enough liquidity.
I'm still short the ZZZs but thinking about covering. Even though the data is indicating a down trend, the 16.57 gap has a major, major down trend priced into the ZZZs.
It looks like the market gave you all of the long ZZZs you were wanting.
Best wishes,
