    This subject was rather thoroughly discussed on this
    list in September 2004.  I suggest you go to the
    archives at
    
    http://www.i-DEADLINK-com/lists/navigation/0409/
    
    and read the threads "Time Sights for Jim T", "Time
    Sight Computations", and "Time sight of the sun, a
    navigator's morsel".
