    Re: 0000 not 2400?
    From: Charles Seitz

    I'll widen things even a bit further.  Why do we
    have East and West longitude?  Longitude should start
    a 0.0 and proceed up to 359.999999999.. degrees just
    as GHA does.
    There is too much culturally induced confusion.  I guess
    that makes life more interesting.
