Abstract
The effect of weak gravitational microlensing on the pulsar timing is considered. The residuals of the times of arrival due to this effect for the pulsar B1937+21 will be ∼10 ns if the time span of observations is about 20 years. It has also been shown that the residuals due to this effect will be several microseconds in the same 20 years in future SKA (Square Kilometer Array) observations of pulsars located behind the bulge.
