Too many dunces trying to talk past the components of the Equation of Time and specifically the distinct rotations that comprise the return of the Sun to a meridian and the varying surface rotation in response to the variable orbital speed of the Earth.

The human mind cannot handle two simultaneous rotations in combination however what the mind can do is isolate each rotation by their traits and infer the combination by their effects whether it is the cause of the seasons or the variations in the total length of each noon cycle.

It is approaching Polar noon at the South pole as the forward motion of the planet turns the surface midway to the circle of illumination on the Solstice. This is how to isolate the orbital surface rotation insofar as its existence visually is swamped by daily rotation.

I was thrilled to see timekeeping evolve through the centuries while visiting the London museums over the weekend and the stature of men who tried their best to work with the observed cycles. This integrity and sense of accomplishment is missing from this era as the mismatch between timekeeping and the planetary cycles have not been dealt with properly before but they have now.
