A pendulum clock gives correct time at the equator. Will it gain time or loose time as it is taken to the poles?

When we take the pendulum to the poles, then time period of the pendulum will decrease. It is because at poles, the gravity decreases and it decreases the time period. As a result, the time clock will gain time.

A hollow sphere filled with water is used as the bob of a pendulum Assume that the equation for simple pendulum is valid with the distance between the point of suspension and centre of mass of the bob acting as the effective length of the pendulum. If water slowly leaks out of the bob, how will the time period vary?
