Thanks Bob and everyone else for their input. The EQT really does change way into the future. I am leaning towards Kevin Karney website: http://www.precisedirections.co.uk/Sundials/index.html using a “Victorian EOT” table adding or subtracting minutes. I could set it into the future 2050 and after that I am sure I will not be around or if the sundial is still standing.
Thanks, Ken Clark Elizabethtown, PA I tried sending this message by AOL account.

However, doing it to the second is pure fiction as the tropical year does not precisely repeat after 4 years cycle ... and any one year in the 4 year cycle is off even more.
