An ID 10-T question. I continually see references to the classic "time site," but none of my texts actually spell out how it was done or the equation(s) used. The best I can surmise is that with a know/given latitude and time, longitude may be determined. Any help on how it was practiced and and the math behind it (list or on-line references) would be appreciated. Thanks Bill
