Is there something wrong with jQuery Datepicker when using UNIX timestamp?

Question

A unix timestamp should only be ten characters, however I keep getting 13 characters and it's causing me issues. How can I fix this?

<script type="text/javascript">
$(document).ready(function()
{
    $("#startdate").datepicker({ altField: "#startdatehidden", altFormat:$.datepicker.TIMESTAMP, dateFormat:$.datepicker.TIMESTAMP, mandatory: true });
});
</script>

Answer 1

Do you mean that you're getting something like 1280943953000 instead of 1280943953?

If yes, that's because javascript counts time in milliseconds, so you should try to
divide the timestamp by 1000
or
substring the last three digits
