+/**
+ File Name: date-003.js
+ Corresponds To 15.9.5.3-1.js
+ ECMA Section: 15.9.5.3-1 Date.prototype.valueOf
+ Description:
+
+ The valueOf function returns a number, which is this time value.
+
+ The valueOf function is not generic; it generates a runtime error if
+ its this value is not a Date object. Therefore it cannot be transferred
+ to other kinds of objects for use as a method.
