Which mechanism enabled accurate timekeeping using sundials historically despite the sun's varying declination?

💡 Explanation

Because the Earth's orbit is elliptical and its axis is tilted, the sun's apparent motion is non-uniform requiring the equation of time application. Therefore accurate sundials incorporated corrections for the equation of time using tables or mechanisms, rather than only gnomon adjustment, precession or altitude compensations.
