Variation of Time with altitude

Time shown by a clock at a height more than that of the mount everest will be ahead of the time shown by the clock at ground level? Or it will be same? Or there will be a difference but very small.?

Answer:

If it is a pendulum clock, the time period will vary with altitude. As the time period of oscillation depends on acceleration due to gravity and the value of g decreases with altitude.
