Date with AM/PM

[SDP2006]

How could I get this to display AM/PM accordingly?

<script type="text/javascript">
var d = new Date()
var hour=new

Array("12","1","2","3","4","5","6","7","8","9","10","11","12","1","2","3","4","5","6","7","8","9"

,"10","11","12")
document.write(hour[d.getHours()])
document.write(":")
document.write(d.getMinutes())
</script>


Thanks

var meridiem = ( d.getHours() < 12 ) ? "AM" : "PM";
