> There is a place in each time zone where noon/midnight *are* (or maybe were) the same each day.
This is incorrect, assuming that you're using "noon" to mean something you can observe with a sundial.

The point where the sun is due north/south varies by ~15 minutes from "mean" noon over the course of a year, due to a) the inclination of the earth's axis and b) the eccentricity of earth's orbit.

When accurate clocks were a new thing, there were clocks which would calculate "sundial time" based upon the day of the year, as sundials were the de facto time standard.
