My solution :

public function getDifference(Zend_Date $date, $part = Zend_Date::SECOND)
{
    $dividers = array(
        Zend_Date::SECOND => 1,
        Zend_Date::MINUTE => 60,
        Zend_Date::HOUR => 3600,
        Zend_Date::DAY => 86400
    );
    if (!isset($dividers[$part])) {
        throw new Zend_Date_Exception('Bad part value');
    }

    $diff = $this->getTimestamp() - $date->getTimestamp();
    if (self::$_options['fix_dst']) {
        $diff += ($this->get(Zend_Date::DAYLIGHT) - $date->get(Zend_Date::DAYLIGHT)) * 3600;
    }

    return $diff / $dividers[$part];
}

Note: $_options is a static property of Zend_Date, there is no method to access it from a derived class.
