* DateTime subclass which supports serialization.
* Currently Propel is not using this for storing date/time objects
* within model objeects; however, we are keeping it in the repository
* because it is useful if you want to store a DateTime object in a session.
* @author Soenke Ruempler
* A string representation of the date, for serialization.
* A string representation of the time zone, for serialization.
* Convenience method to enable a more fluent API.
* @param string $date Date/time value.
* @param DateTimeZone $tz (optional) timezone
public static function newInstance($date, DateTimeZone $tz = null)
return new DateTime($date, $tz);
return new DateTime($date);
* PHP "magic" function called when object is serialized.
* Sets an internal property with the date string and returns properties
* of class that should be serialized.
// We need to use a string without a time zone, due to
// PHP bug: http://bugs.php.net/bug.php?id=40743
$this->dateString = $this->format('Y-m-d H:i:s');
$this->tzString = $this->getTimeZone()->getName();
return array('dateString', 'tzString');
* PHP "magic" function called when object is restored from serialized state.
* Calls DateTime constructor with previously stored string value of date.
parent::__construct($this->dateString, new DateTimeZone($this->tzString));
