Dear John, Your question intrigues me...
> The sundial will be located at local meridian > (longitude) -77.0769 degrees. If it had a > normal time zone, the Standard Meridian would > be -75 degrees (UT+ 5 hrs.). True. > But since its Time Zone is UT +5:30, then > wouldn't its Standard Meridian be (75 + 7.5) > = -82.5 degrees? Is this correct? True again. The reason for being intrigued is that very few sundial features depend on the longitude or time zone. Generally, these things matter only when you are explaining to clients why sundials don't indicating the same time as that shown on their watches! What does the software do with the information? Are you proposing to decorate your design with an analemma (perhaps several) that indicates time zone time?
