javascript toLocaleDateString output format YY-MM-YYYY

Status changed to 'Confirmed' because the bug affects multiple users.

There is more info on this posted in this Zotero Forum:

Basically, if you put in a date as a string like "July, 2 2010" with the command [code]var d = new Date("July 2, 2010")[/code], the method [code]d.toLocaleDateString()[/code] gives the output "10-07-2010".

Dan at zotero wrote the code:
""
<pre id="output"></pre>
<script>
var str = "";

var d = new Date("July 2, 2010");

str += "Date is " + d + "\n\n";
str += "toLocaleString: " + d.toLocaleString() + "\n";
str += "toLocaleDateString: " + d.toLocaleDateString() + "\n";

document.getElementById('output').appendChild(document.createTextNode(str));
</script>
""

which produces an output of
""
Date is Fri Jul 02 2010 00:00:00 GMT-0700 (PDT)

toLocaleString: Fri 02 Jul 2010 12:00:00 AM PDT
toLocaleDateString: 10-07-2010
""

With the reminder from other people updating, I retested this. Same issue using Ubuntu 11.10 and FF 9.0.1 with latest updates
$echo $LANG
en_CA.UTF-8
$ echo $LANGUAGE
en_CA:en
This is from an 'out of the box' install of Ubuntu to a VirtualBox VM.
Since there are so few people noticing, this **really** looks like an issue related to locale en_CA
I guess I need to spin up a new Ubuntu VM with alternate settings to confirm

Got that new VM created.

Works just fine:

Ubuntu 11.10 and FF 9.0.1 with latest updates
$echo $LANG
en_US.UTF-8
$ echo $LANGUAGE
## blank ##

VERY strong indication that the problem is related to locale information. en_CA fails, en_US works.
Anyone have an idea about what 'package' this really belongs with? I could put it under one of the javascript packages instead of firefox, but it really belongs to a lower level. I just do not know which underlying library toLocaleDateString belongs to or calls. I add javascript and locales.

Sigh ... Something ELSE that should be in my web application cross browser / cross OS internationalization testing, but is just too big to be reasonable.

I have this problem too running Lubuntu 11.10 and Firefox 10.0.2. Happens with the Zotero plugin.

Enter the date in ISO format 2011-01-15...click out of the field and it shows 11-01-2011.

Oh, I guess I should add that my system locale is: en_CA.utf8

I have this problem too, using Linux Mint with Firefox 12 and only Firebug installed. I have the `en_CA.UTF-8` locale.

javascript-common package only expose /usr/share/javascrit content in /javascript URL.
That bug is not related to that package.
