ECMA Section: 15.9.5.3 Date.prototype.toDateString()
|
|
Description:
|
|
This function returns a string value. The contents of the string are
|
|
implementation dependent, but are intended to represent the "date"
|
|
portion of the Date in the current time zone in a convenient,
|
|
human-readable form. We can't test the content of the string,
|
|
but can verify that the string is parsable by Date.parse
|
|
|
|
The toDateString 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.
