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,
