Incorrect timezone in Firefox, compared to Safari, using javascript Date()

The following code

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

gives me

Sun Mar 06 2011 21:41:36 GMT+1300 (NZST) {}

in Firefox, but

Sun Mar 06 2011 21:40:51 GMT+1300 (NZDT)

in Safari (which is correct).

My system Date & Time is set to NZDT, so I'm wondering where firefox is getting its NZST from. Mind you, the UTC offset (+1300) is correct in both cases.

How can I get Firefox displaying the correct timezone: NZDT?

This was a bug that was fixed in Firefox v4 and later.

You shouldn't rely on that output as it's different in other browsers (IE), instead you should use the getTimezoneOffset method.

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

The offset will change with day light savings but there are ways to work with this.

If everything is how you want it except for the "NZST", you could just do a simple text replace:

console.log(date.toString().replace('NZST', 'NZDT'));

Note that this is really only simple fix for the display issue, it doesn't address the underlying cause.
