Jquery倒计时插件，来自Mysql数据库的日期

I'm trying to modifie the JS script so I can get the date from a database instead of typing it manually. I don't really know how to get right format on the date. The plugin only use days, hours, minutes, seconds.

Is there someone that can help me?

Jquery countdown plugin

Original:

$(function () {
var austDay = new Date();
austDay = new Date(austDay.getFullYear() + 1, 1 - 1, 2);
$('#defaultCountdown').countdown({until: austDay});
$('#year').text(austDay.getFullYear());
});

</script>

Modified:

<?php $waa = '1441894898' ?>

<script>

$(function () {
var austDay = <?php echo json_encode($waa); ?>;
$('#defaultCountdown').countdown({until: austDay});
});
</script>

The plugin don't only use years, months, etc..., but a javascript Date (reference here) instance. So if your $waa variable is the date from what you want to count down, and it is in milliseconds, the var austDay = new Date(<?php echo $waa; ?>); code should work.

That is mostly easily done with strtotime as it will pretty much recognize any time format you want. Then you can output it anyway you want. I use the following

date(MM/DD/YY, strtotime($waa))

For you it would most likely look like this

<?php echo json_encode(date(MM/DD/YY, strtotime($waa))); ?>

Not sure what format you need the date in but you can use the manual for date to get the format of the date you need right. (http://php.net/manual/en/function.date.php)
