Set defaultCountdown jquery countdown to specfic time

I have a countdown timer set up to finish on the 1st of october.

    <script type="text/javascript" src="Count/jquery.countdown.js"></script> 
    <script type="text/javascript"> 
    $(function () {
        var austDay = new Date();
        austDay = new Date(2011, 10-1, 01)
        $('#defaultCountdown').countdown({until: austDay});
        $('#year').text(austDay.getFullYear());
    });
    </script> 

However, how do i set it to finish not at midnight but at 9am on 1st October 2011?

Thanks

new Date(year, month, day, hours, minutes, seconds, milliseconds)

Just set all those.

Also, why are you doing 10-1? That is september, not october.
