If someone gives me the definition of Solar Time, you can have that too. I'm a programmer, not an astronomer  |
Terry,
The guts of Solar time is how the position of the sun deviates from where our clocks say it should be due to the eccentricity of the earth's orbit. The formula for that deviation is called the "Equation of Time" and it can be found here:
http://en.wikipedia.org/wiki/Equation_of_time
If you simply apply the equation of time adjustments to local (standard) time you will get the "rough" solar time based on the central meridian of the time zone.
To make it more accurate, start with UTC, apply the equation of time then adjust for the required longitude (i.e. add 1 hour for each 15 degrees east).
Hope this helps,
Al.
