+  20.3.2 The Date Constructor
+
+  ...
+
+  The Date constructor is a single function whose behaviour is overloaded based
+  upon the number and types of its arguments.
+
+  The Date constructor is designed to be subclassable. It may be used as the
+  value of an extends clause of a class definition. Subclass constructors that
+  intend to inherit the specified Date behaviour must include a super call to
+  the Date constructor to create and initialize the subclass instance with a
+  [[DateValue]] internal slot.
