The rotational effects (also known as frame dragging) are probably negligible, given that it took the Gravity Probe B 7 years of data analysis to confirm its detection using dedicated equipment.
The gravitational effect on time of flight, known as the Shapiro time delay is of the order of 2GM/c^3, where M is the mass of the Earth, or about 0.03ns, too small to matter.
