I believe that local time in North Carolina is kept at GMT -4 during the summer, so the test period begins at 2100-Local and ends at 2300-Local.

That position is about 85 nm offshore. The 246nm radius
includes all of the North Carolina coast, most of the South
Carolina and Virginia coast, and up to 160 mn inland, including
the Raleigh-Durham area.
