A location along longitude does NOT rotate to face the Sun every 24
hours.

Our ancestors ASSUMED constant axial rotation and corrected it by the
Equation of Time hence there is no external reference for axial
rotation through 360 degrees ,neither against the Sun nor the stars.

It may eventually dawn on somebody that the Equation of Time format
based on axial rotation/terrestial longitudes precedes the
calendrically based sidereal system or rather the sidereal format is
based on the 24 hour/360 degrees equivalency.

Big topic,small people ( at least so far).
