This year empiricists will attempt to erase an entire timekeeping culture and its links to planetary dynamics and external references much like those thugs in the Middle East try to erase the culture of an ancient civilization. Instead of sledgehammers the polished scam merchants conjure up stories to suit an agenda, in this case introducing a speculative hypothesis about the rotation period of the Earth in Jurassic times and then ending with an idealized rotation of 24 hours in the year 1820 -
"At the time of the dinosaurs, Earth completed one rotation in about 23 hours," says MacMillan, who is a member of the VLBI team at NASA Goddard. "In the year 1820, a rotation took exactly 24 hours, or 86,400 standard seconds. Since 1820, the mean solar day has increased by about 2.5 milliseconds." NASA

There is no 'decision' next November about detaching timekeeping from planetary dynamics as these brutes have already detached rotation from the antecedent principles hence sledgehammer empiricism at its worst.
The foundations of timekeeping and external references is based on a single astronomical event which is closely tied to the Equinox event. It is how to define the Earth's position in space using a line-of-sight observation where stars appear from behind the Sun or its glare at a specific point in the Earth's orbit, in this case the first appearance of Sirius fulfilled this requirement. Then the number of times the planet turns to bring Sirius into view emerges after that which in turn creates a divergence between the calendar framework and the raw fact of close to 365 1/4 rotations within an orbital circumference.
Men can stop behaving like thugs and brutes determined to erase the astronomical foundations of timekeeping but the world becomes so much sterile and dreary. Unlike the historical artifacts which were lost to bulldozers, drills and hammers, every single bit of astronomy can be restored and improved on by some of the people who up to now have launched an assault on a heritage which is both robust and fragile by turns.
