Hi to everyone on the Sundial mailing list. I have a question regarding the Equation of time correction that I hope someone may be able to answer for me.
The correction of time is predominantly determined by the result of two separate effects. (a) the eccentricity of the orbit of the earth around the sun. (b) the tilt of the earth axis relative to the path around the sun. To find the complete Equation of time the above two effects are added together. My question is with regard to the tilt of the earth axis effect. The SUNDIAL AUSTRALIA ISBN 0 646 22200 7 book indicates that (for the tilt of the earth axis effect) there is no difference between local noon and solar noon at dates corresponding to the Equinoxes and Solstices (4 times per year), but produces a difference of up to +/- 9.86 minutes between each Equinox and Solstice (4 times per year). Can someone please explain and describe the above effect.
