    Re: Sumner's Line (Navigation question)
    From: Bill B

    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
