       * epoch of 1970-01-01T00:00:00Z and nanosecond fraction of second.
       * <p>
       * This method allows an arbitrary number of nanoseconds to be passed in.
       * The factory will alter the values of the second and nanosecond in order
       * to ensure that the stored nanosecond is in the range 0 to 999,999,999.
!      * For example, the following will result in the exactly the same instant:
       * <pre>
       *  Instant.ofEpochSecond(3, 1);
       *  Instant.ofEpochSecond(4, -999_999_999);
       *  Instant.ofEpochSecond(2, 1000_000_001);
