Answer / hari
Go Slow, Because when altitude is increased gravitational
force will decreases.

Answer / arun k s
Go slow if it is a pendulum clock, because when altitude
increases, gravitational force decreases. This will
increase the time period of the pendulum, which takes more
time to swing than earlier.

"The prediction was tested in 1962, using a pair of very
accurate clocks mounted at the top and bottom of a water
tower. The clock at the bottom which nearer the earth, was
found to run slower, in exact agreement with general
relativity." A Brief History of Time, Stephen Hawking. 1989
So the clock at the top of the mountain would run faster
relative to the bottom.

Answer / vidya
The mountain clock will run faster IF COMPARED TO A SEA LEVEL CLOCK because the flow of TIME is Slowed by gravity and the gravity is slightly less on the mountain top. The flow of time affects ALL processes though, so compared to the (local) speed of light, or (any other mountain top measurement) the clock will appear to run exactly at the same rate. It is only a RELATIVE measurement (compared to the sea-level clock) that would show a different rate. The Scientists Pound-Rebka at Harvard University verified this effect with an atomic clock experiment. The effect would be WAY WAY too small to see with an ordinary clock though. It might take millions of years to see a one-second difference in two ordinary clocks.
