+
+   The [[Class]] property of the newly constructed object

+   5. Call ToNumber(minutes)
+   6. Call ToNumber(seconds)
+   7. Call ToNumber(ms)
+   8.  If Result(1) is NaN and 0 <= ToInteger(Result(1)) <=
+   99, Result(8) is 1900+ToInteger(Result(1)); otherwise,
+   Result(8) is Result(1)

+   Description:        The [[Prototype]] property of the newly constructed

+   the one that is the initial value of Date.prototype.
+
+   The [[Class]] property of the newly constructed object

+   2. Call ToNumber(month)
+   3. Call ToNumber(date)
+   4. Call ToNumber(hours)
+   5. Call ToNumber(minutes)
+   6. Call ToNumber(seconds)
+   7. Call ToNumber(ms)
+   8.  If Result(1) is NaN and 0 <= ToInteger(Result(1)) <=
+   99, Result(8) is 1900+ToInteger(Result(1)); otherwise,
+   Result(8) is Result(1)
+   9.  Compute MakeDay(Result(8), Result(2), Result(3)
+   10. Compute MakeTime(Result(4), Result(5), Result(6),

+   11. Compute MakeDate(Result(9), Result(10))
+   12. Set the [[Value]] property of the newly constructed

+
+
+   This tests the returned value of a newly constructed
+   Date object.

+   Description:        The [[Prototype]] property of the newly constructed

+   the one that is the initial valiue of Date.prototype.
+
+   The [[Class]] property of the newly constructed object is
+   set to "Date".
+
+   The [[Value]] property of the newly constructed object is
+   set as follows:
+
+   1. Call ToPrimitive(value)
+   2. If Type( Result(1) ) is String, then go to step 5.
+   3. Let V be  ToNumber( Result(1) ).
+   4. Set the [[Value]] property of the newly constructed
+   object to TimeClip(V) and return.
+   5. Parse Result(1) as a date, in exactly the same manner
+   as for the parse method.  Let V be the time value for
+   this date.
+   6. Go to step 4.

+   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()

+   Description:
+
+   If mon is not specified, this behaves as if mon were specified with the
+   value getMonth( ). If date is not specified, this behaves as if date were
+   specified with the value getDate( ).
+
+   1.   Let t be the result of LocalTime(this time value); but if this time
+   value is NaN, let t be +0.
+   2.   Call ToNumber(year).
+   3.   If mon is not specified, compute MonthFromTime(t); otherwise, call
+   ToNumber(mon).
+   4.   If date is not specified, compute DateFromTime(t); otherwise, call
+   ToNumber(date).
+   5.   Compute MakeDay(Result(2), Result(3), Result(4)).
+   6.   Compute UTC(MakeDate(Result(5), TimeWithinDay(t))).
+   7.   Set the [[Value]] property of the this value to TimeClip(Result(6)).
+   8.   Return the value of the [[Value]] property of the this value.

+   [[Class]] property is "Date". Also, the phrase "this time value" refers
+   to the number value for the time represented by this Date object, that is,
+   the value of the internal [[Value]] property of this Date object.
