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.
