I suppose it could be the Daylight Saving Time factor except that New York and Pittsburgh (as well as all of Florida & the East Coast) all switch to Standard Time simultaneously.....in other words, they ought to be the same at the same time of the year.

AJ, all states or portions of all states in the Eastern zone do no go on EDT. In fact that is true in three of the four time zones in the US. The eastern portion of Indiana did not go on EDT when I was stationed there. It would be difficult to program a World Clock for EDT.
