I'm in the Eastern time zone, USA, and it definitely is counting down to 6 PM Eastern time.  For the record, unless you're delaying things two hours in the Eastern time zone, a time of 6 Central could not correspond to 5 Eastern.  That's backwards.  It would have to be either 6 PM EST/5 PM CST or 6 PM CST/7 PM EST or 5 PM EST/4 PM CST.
