  24     ECMA Section:       15.9.5.3-2 Date.prototype.valueOf
  25     Description:
  26
  27     The valueOf function returns a number, which is this time value.
  28
  29     The valueOf function is not generic; it generates a runtime error if
  30     its this value is not a Date object.  Therefore it cannot be transferred
  31     to other kinds of objects for use as a method.
