You can do this inside a Sideview Utils HTML module to get a single date picker:
<script>
$$(function() {
$$( "#datepicker" ).datepicker();
});
</script>
<p>Date: <input type="text" id="datepicker" /></p>
That's the sample code from http://jqueryui.com/datepicker/, customize as needed.
Do you have sample or example for the date time picker? if so please post
