Assuming that your dates are in the form "year-month-day", this is how you 
would transform the dates properly:

while($r = mysql_fetch_assoc($query)) {
    $temp = array();
    $dateArray = explode('-', $r['date']);
    $year = $dateArray[0];
    $month = $dateArray[1] - 1; // subtract 1 from the month to convert to 
javascript date format
    $day = $dateArray[2];

    $temp[] = array('v' => "Date($year, $month, $day)");
    $temp[] = array('v' => (int) $r['value']);
    $rows[] = array('c' => $temp);
}
