Narrative:

ZNY issued a clearance to cross 10 NM west of lancaster at 12000 ft. The first officer was flying and entered the restr in the FMC as 10 NM east of lancaster at 12000 ft. I did not verify the FMC entry. The controller issued a vector off course when she realized that we would not make the restr.
