Quizplus · Accepted Answer

When a pendulum clock is placed at a higher altitude, it experiences slightly lesser gravitational force than at sea level. As a result, the length of the pendulum becomes slightly longer, and the time period of the pendulum increases. The clock, therefore, starts to lose time, and the error accumulates over time. This effect is known as the "gravitational time dilation" and has been experimentally confirmed.
