    Nautical Almanac Format
    From: Chuck Taylor
    Date: 2004 Sep 21, 20:03 -0700

    The various editions of Bowditch include extracts from
    the (U.S.) Nautical Almanac.  The 1943 and prior
    editions show one format (including the Sun's
    Declination and Equation of Time for every 2 hours,
    and the "Right Ascension of the Mean Sun + 12 hours"
    for each day).  The 1962 and subsequent editions show
    the modern format of GHA of the Sun, Moon, Aries,
    Venus, Mars, Saturn, and Jupiter listed every hour.
    In what year did the change in format take place?
