S. Naval Observatory:   # eqt = -105.8 * sin(l) + 596.2 * sin(2 * l) + 4.4 * sin(3 * l)   # -12.7 * sin(4 * l) - 429.0 * cos(l) - 2.1 * cos (2 * l)   # + 19.3 * cos(3 * l);   # where l is the "mean longitude of the Sun" given by   # l = 279.642 degrees + 0.985647 * d   # and d is the interval in days from January 0, 0 hours Universal Time   # (equaling the day of the year plus the fraction of a day from zero hours).
