ECMA Section: 15.9.5 Properties of the Date prototype object
Description:
The Date prototype object is itself a Date object (its [[Class]] is
"Date") whose value is NaN.
The value of the internal [[Prototype]] property of the Date prototype
object is the Object prototype object (15.2.3.1).
In following descriptions of functions that are properties of the Date
prototype object, the phrase "this Date object" refers to the object that
is the this value for the invocation of the function; it is an error if
this does not refer to an object for which the value of the internal
[[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.
