I apologize for the confusion around EST/EDT. It is too late to fix/change it. Unfortunately those of us in north america almost always refer to the zones as PST/CST/EST/etc regardless of daylight savings. It's a name for the time in the area year round, regardless of the technicality around DST.
I don't mean to be disrespectful, and I have no stake in this, but being in the US myself, I will categorically state that you are wrong here.
It's a common problem, but anybody with any knowledge about time, ESPECIALLY people in the computer/programming field, need to know that there's a HUGE difference between EST and EDT, and the time zone (Eastern Time Zone).
Like I said, I have ZERO stake in this, and so am just a potential arbiter, and you are wrong on this point.
