[time-nuts] Q/noise of Earth as an oscillator

The discussion of Earth as a system with Q, but which is not resonant,
is a more extreme case than the CONICAL PENDULUM.

The conical pendulum has a simple form of a weight on a string, instead of oscillating 
in one plane as a conventional pendulum, it swings around in a circular orbit 
in the horizontal plane. It has a definite resonant frequency.
Now a simple pendulum oscillates kinetic energy and potential energy, but a conical pendulum
has constant potential energy and oscillates its energy from North-South energy to East-West 
I believe that a conical pendulum still has the circular error associated with amplitude.

But will it be as good a time keeper as the simple pendulum?

A curious fact about the conical pendulum is that whereas the simple pendulum has earth 
rotation forces that show in the Foucault Pendulum, the conical pendulum has a different 
period depending whether is swings clockwise or anticlockwise due to the earths rotation.

What do you think?
