Joe:

A day is measured by the earth rotating about its axis.

The year is measured by the earth rotating about the sun's axis.

So which rotation is responsible for the leap-second?

Are the rotations linked or mutually exclusive?

The moon slows the earth's rotation due to the gravitational propagation
delay. Does it also cause the earth to take longer to go around the sun?

The moon is at it's point of lowest rotational potential with respect to the
earth. Relative to earth, the moon does not rotate, we always see the same
face.

The earth is striving for its lowest rotational potentail with respect to
the sun. Eventually, the earth will stop rotating and one side will always
face the sun.

I think Texas will wind up where the sun doesn't shine.

Amen!
