code: public BigDecimal getDecimalSecond()
      {
          BigDecimal sec = BigDecimal.valueOf(_second);
          if (_fraction != null)
          {
              sec = sec.add(_fraction);
          }

      }
docs: Returns the seconds of this Timestamp.
  <p>
  Seconds are not affected by local offsets.
  As such, this method produces the same output as
  {@link #getZDecimalSecond()}.
  
  @return
  a number within the range [0, 60);
  0 is returned if the Timestamp isn't precise to the second
  
  @see #getZDecimalSecond()
