/**
   File Name:          15.9.4.2.js
   ECMA Section:       15.9.4.2 Date.parse()
   Description:        The parse() function applies the to ToString() operator
   to its argument and interprets the resulting string as
   a date.  It returns a number, the UTC time value
   corresponding to the date.

   The string may be interpreted as a local time, a UTC
   time, or a time in some other time zone, depending on
   the contents of the string.

   (need to test strings containing stuff with the time
   zone specified, and verify that parse() returns the
   correct GMT time)

   so for any Date object x, all of these things should
   be equal:

   value                       tested in function:
   x.valueOf()                 test_value()
   Date.parse(x.toString())    test_tostring()
   Date.parse(x.toGMTString()) test_togmt()

   Date.parse(x.toLocaleString()) is not required to
   produce the same number value as the preceding three
   expressions.  in general the value produced by
   Date.parse is implementation dependent when given any
   string value that could not be produced in that
   implementation by the toString or toGMTString method.

   value                           tested in function:
   Date.parse( x.toLocaleString()) test_tolocale()
