not working on iOS

[SShady666]

in safari it shows Invalid Date

in html head I used
<script type="text/javascript" src="http://www.datejs.com/build/date.js"></script>

the code that I used to show the date and time
$('#update_date_time').html(new Date(data.data.update_date_time).toString("hh:mm tt"));

issue is only on Safari (tested only in XSMax)
