I want to design an altitude dial that will indicate local clock time. I was thinking of an oversized pillar or shepherd's dial or a large ring dial. Usually these are portable, but I want to make one for my particular location (Lat 38d53m48s N, Long 121d04m33s W).
What types of corrections do I need to know about to get it to read the local clock time? I am assuming that I will need to know whether it's Daylight Savings time (I'm in the U.S.). Anything else? The Equation of Time only applies to azimuth dials, not altitude dials, right? Any hints, references, or helpful suggestions appriciated. Tom Bower, Auburn, California P.S. I'm not an expert, so I really like reading the mail from such friendly and knowledgeable people. Thanks in advance!
