Pat, An answer on several of your questions you can find on http://www.fransmaes.nl/zonnewijzers/welcome-e.htm
About the question of standard time and daylight saving time: a good analemmatic sundial indicates only solar time. For standard time and daylight saving time we have a watch! The sundial is the only simple instrument that indicates solar time. Changing it to indicate standard time is similar to an astronomer who turns his device to indicate the sidereal time into a standard time clock.
