  24     ECMA Section: 15.9.5.7 Date.prototype.toLocaleTimeString()
  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.toLocaleTimeString()  ==  d.toString()
  31
  32     The only headache is that as of this writing the "GMT ..."  portion of
  33     d.toString() is NOT included in d.toLocaleTimeString() as it is in
  34     d.toTimeString(). So we have to take that into account.
