This today from http://www.cyberspaceorbit.com/
"As Earth's rotational momentum begins to decrease, the law of the conservation of energy should cause core
temperatures and subsequent geologic stress to increase in an inversely proportional manner.
Over the next 6 months, take note if normally accurate time pieces increasingly gain time relative to the
"observed" rate of Earth's spin. As an experiment, you may wish to leave TWO precisely set, independently
ACCURATE time pieces unrecalibrated with any future time-checks to serve as benchmarks. Over the next 6
months, compare "official" time sources (Internet atomic clocks) against these benchmark time pieces to observe
and track if there is a steady increase in the amount of time they gain with each passing month."
Is atomic time changing wrt astronomical time?!
