  24     ECMA Section: 15.9.5.4 Date.prototype.toTimeString()
  25     Description:
  26     This function returns a string value. The contents of the string are
  27     implementation dependent, but are intended to represent the "time"
  28     portion of the Date in the current time zone in a convenient,
  29     human-readable form.   We test the content of the string by checking
  30     that d.toDateString()  +  d.toTimeString()  ==  d.toString()
