    Re: Spur of the moment long by chron

    I suspect that "time sight" is a North American term. If I open my 1958 copy of Bowditch I have no difficulty finding an entry headed "Time Sight." However none of my British books use the expression.

    In British practice the terms "Longitude method", "Chronometer method" and "Longitude by Chronometer" were used interchangeably.

    The earliest copy of Nicholls's that I have is dated 1930. By this date position line methods were being taught in detail. The Longitude method was one of several methods being taught to obtain a celestial position line. The Longitude method and the intercept method each had their own chapter.
