How does Date.toLocaleDateString() work?

问题:

I've to represent the date with local user's configurations. Follows the MDN description:

The toLocaleDateString method relies on the underlying operating system in formatting dates. It converts the date to a string using the formatting convention of the operating system where the script is running. For example, in the United States, the month appears before the date (04/15/98), whereas in Germany the date appears before the month (15.04.98).

I do this:

var date = new Date ();
console.log (date.toLocaleDateString ());

It prints out Saturday, October 13, 2012 but what I expect is Sabato, 13 Ottobre, 2012 (that's the Italian date format). Now, configurations of my browser and my system are set properly (Italian language and the above format date) so I don't understand how does toLocaleDateString work.

Am I doing it right?

According to the Mozilla documentation, the format can vary wildly depending on the user's location and computer settings.

The exact format depends on the platform, locale and user's settings.

This question is out-of-date.

These are my tests:

(new Date ()).toLocaleDateString () -> "4/9/2013" (italian format 'd/m/Y') with Chrome 29
(new Date ()).toLocaleDateString () -> "mercoledì 4 settembre 2013" (italian format 'D d M Y') with Firefox 22

It works with newest browsers versions.
