Well I tried what I said would work and found a problem.
The moon moves 3/5 deg/hr and parallax can be as much as +/- 1 deg depending on observers location relative to the moon. So you can not treat parallax as a perturbation on a time calculation. They time and position must be handled simultaneously in a single calculation.
