You must be kidding, of course. You are far, far from being the first person to figure this out, but as usual, you are completely off-base as to the actual reason. The rest of us know that because of the Earth's various speeds along the ecliptic at different times of the year, it takes either a little less than 24 hours or a little more than 24 hours for the Sun to attain culmination on the meridian.

Regarding the equation of time, it has been fully understood for a long, long time. You have not discovered anything new.

The rest of us indeed !,the 'new' idea that the Earth turned once
exactly in 24 hours in the year 1820 and is slowing down relative to
that historical point is more of the same from the fiction generating
empirical machine and impossible to contend with - no class,no
intellectual integrity,no historical or referential depth,just people
making assertions to fill in gaps for whatever purpose they wish,in
this case the civil convenience -

"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

I don't think in terms of discovery,the working language of planetary
dynamics requires modifications and especially when it is possible to
see these things in action hence the modification from axial
precession to an annual orbital component and from there into
multiple other consequences.You poor soul interpreted the orbital
turning of Uranus to the central Sun as a changing perspective due to
the orbital motion of the Earth but I assure you that Uranus will
continue to turn a full 360 degrees over the next 8 decades.

This is new and it is hugely important for a range of topics from the
tides to a climate spectrum and that is why urgency is needed to
isolate the predictive section of astronomy from the interpretative.If
you can't keep up then go your own way and enjoy your telescope but
don't assume you are speaking for a group of individuals with a firm
intellectual grasp on things,most likely they are welfare academics
doing just enough to get away with a salary and an unwarranted
reputation as 'astronomers' or 'planetary scientists'.Modern imaging
is the fresh air that drives out the stale atmosphere of Royal Society
empiricism,at least the vicious strain that give mathematicians and
their non geometric language dominance in astronomy.This is good,this
is all good.
