Notes


      Notes: Julian seconds (not an official unit) serve the
        same purpose as Julian Days, interval computations.
        The zero point is 0:00 1 Jan 2000, so js < 0 before then.
        Julian Seconds are double precision and have a precision
        better than 1 millisecond over a span of +/- 1000 years.
        A precision warning may point to a call to dt_tm_fromjs.
     
      See also ymds2js, dt_tm_tojs, dt_tm_fromjs, jscheck.
