If you use a version prior to 5.3 you can make __wakeup and __toString work using the following piece of code.

<?php
class ExtendedDateTime extends DateTime {
    private 
$_date_time;
    
    public function 
__toString() {
        return 
$this->format('c'); // format as ISO 8601
    
}
    
    public function 
__sleep() {
        
$this->_date_time $this->format('c');
        return array(
'_date_time');
    }
    
    public function 
__wakeup() {
        
$this->__construct($this->_date_time);
    }
}
?>

Hope this helps someone.

Be aware, even though this __wake() method exists as of PHP 5.2, DateTime objects don't retain their values when unserialized under PHP 5.2. PHP 5.3 fixes this.
