To be fair to you,the mistake is a really old one and precedes the
gravitational agenda (which makes use of the mistake) by a decade.The
first professional astronomer was Flamsteed who set out to prove that
the Earth rotates constantly on its axis through the motion of the
fixed stars thereby making use of this observation for determining
planetary longitude.
Flamsteed was incorrect.

I did many times -
... our clocks kept so good a correspondence with the Heavens that I
doubt it not but they would prove the revolutions of the Earth to be
isochronical"
http://www-gap.dcs.st-and.ac.uk/~history/HistTopics/Longitude2.html
A direct consequence of that statement can be found in any website
refering to the sidereal value -

You won't find any,there is just myself.
You can however appeal to those who are familiar with the equable 24
hour clock day,the Equation of Time correction from the noon
determination and how one 24 hour day elapses seamlessly into the next
24 hour day by the 'Equation of Time' method but then you will
encounter those who are aware that the precise value for axial
rotation through 360 degrees,is and always will be 24 hours.
