  24     ECMA Section:       15.9.5.2 Date.prototype.toString
  25     Description:
  26     This function returns a string value. The contents of the string are
  27     implementation dependent, but are intended to represent the Date in a
  28     convenient, human-readable form in the current time zone.
  29
  30     The toString function is not generic; it generates a runtime error if its
  31     this value is not a Date object. Therefore it cannot be transferred to
  32     other kinds of objects for use as a method.
