41 File Name: 15.9.5.2.js
42 ECMA Section: 15.9.5.2 Date.prototype.toString
44 This function returns a string value. The contents of the string are
45 implementation dependent, but are intended to represent the Date in a
46 convenient, human-readable form in the current time zone.
48 The toString function is not generic; it generates a runtime error if its
49 this value is not a Date object. Therefore it cannot be transferred to
50 other kinds of objects for use as a method.
