..weigh less and the pendulum will swing at a slower rate. It might become more valuable (high mountain areas have less access to fine clocks than many sea level communities).
it will lose time. it slows as you change level....change of gravity

The acceleration of gravity decreases as the observation point is taken deeper beneath the surface of the Earth, but it's not the location of the compound pendulum that's responsible for the decrease.
A swinging pendulum encounters "friction" called drag in air. It will do so in water, too. It's just that the viscosity of the air is so much less than that of water, so the pendulum moves with a ton more drag in water. It will move much more slowly in water, and will come to a stop dramatically sooner than an identical pendulum swung in air.

The time period of a pendulum will increase when taken to the top of a mountain. This is because the acceleration due to gravity decreases at higher altitudes, resulting in a longer time for the pendulum to complete each oscillation.
No. It will run 2.45 times as SLOW.
The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.
The pendulum will take more time in air to stop completely in comparision with water

The original 'water clocks' and sundials are ideas taken from old civilizations. But the more recent ones run by pendulum or by springs were hypothesized by Robert Hooke. He worked on the principle of springs and defined and improved the then pendulum. So, he might be called the founder of clocks.
A Froude pendulum is a simple pendulum suspended in a rotating shaft (taken from: VIBRATION OF EXTERNALLY-FORCED FROUDE PENDULUM, International Journal of Bifurcation and Chaos, Vol. 9, No. 3 (1999) 561-570)
This pendulum, which is 2.24m in length, would have a period of 7.36 seconds on the moon.
if by arc you mean the "Period" of the pendulum then yes, it does: with each revolution the period of the pendulum (the time taken to swing back and forth once) does decrease.
Increases.
