15 minute interval drop down?

[homer09001]

i thought this would be a very simple thing to find on the net, aparently not so.

I need a drop down box that displays every hours of the day 0 - 2345 obviously in 15 minutes intervals.

0015
0030
0045
0100
and so on and so forth.

For the life of me though i can't find anything like this already together on the net and can't figure out how to write it myself.

Any pointers would be greatly appreciated.

Problem solved, found an hour code and managed to modify it:

<?
$id = $_REQUEST['hour'];

function createHours($id='hours_select', $selected=null)
    {
        /*** range of hours ***/
        $r = array("00","01","02","03","04","05","06","07","08","09",10,11,12,13,14,15,16,17,18,19,20,21,22,23);
		$m = array("00",15,30,45);

    $select .= "<select>";
    foreach ($r as $hour)
    {
		foreach($m as $min)
		{

        	$select .= '<option value="'.$hour.':'.$min.'">'.$hour.':'.$min.'</option>';

		}
    }
    $select .= '</select>';
    return $select;
}

echo createhours();

?>
