Excellent point, Martin! And in fact it is the precision and stability
of modern "atomic" clocks that permit geophysicists to measure that
varying Earth rotation rate (and thus the varying length of the common
"day").

I don’t think so – the earth is slowing down and the rate of slow-down
can be measured. It follows therefore that the earth therefore cannot
be used as THE clock by which time is defined.

I will only invest in nukes that are 150 gigameters away. How much solar
energy have you collected today?
Id put my money on the sun and solar energy. What a source of power! I
hope we dont have to wait til oil and coal run out before we tackle
that. I wish I had a few more years left. -- Thomas Edison♽☯♑
