What's fascinating about certain cranks is that just when you think
you've seen all the absurdities they can come up with, they manage to
produce something even worse. Their cognitive dissonance and ability
to pull out bizarre notions from who knows where, on top of a
perfectly well-defined technical procedure, is astonishing. We've seen
this before with GPS, where Hachel invents all sorts of fantasies,
like atomic clocks in the receivers or synchronization with a clock
infinitely far away in a fourth spatial dimension...

described by Einstein in his 1905 paper, discussions that took place
17 years ago and more recently on sci.physics.relativity and
fr.sci.physique.

Taking 2 identical pendulum clocks blows
this pathetic bullshit out.

 
 
Not at all. A pendulum by itself is not a clock. The
system Earth-Pendulum is.

Indeed. Pendulum clocks cannot serve as absolute time keepers,
since they need to be calibrated against a real clock.
(such as the motions of the Earth)
They can only serve to interpolate between astronomical observations.

Man-made clocks of better accuracy than the Earth
didn't become available until the late 1930-ies.
All talk of the relevance of real clocks to Einstein 1905
is hogwash,
