You are doing the math backwards. LOL! When it is 11:56 pm here in the east, it is 8:56pm on the west coast. So you can actually see the speech in prime time. Be warned that CSPAM is notorious for switching the President's remarks from their posted times. But this one is too important for them to mess with, I hope.
A good Homer Simpson 'D'oh!' is in order. Thanks.
