I don't understand the 60 there, can you explain that please?

I was based on Mage_Core_Model_Resource_Session:getLifeTime

public function getLifeTime()
    {
        if (is_null($this->_lifeTime)) {
            $configNode = Mage::app()->getStore()->isAdmin() ?
                    'admin/security/session_cookie_lifetime' : 'web/cookie/cookie_lifetime';
            $this->_lifeTime = (int) Mage::getStoreConfig($configNode);

            if ($this->_lifeTime < 60) {
                $this->_lifeTime = ini_get('session.gc_maxlifetime');
            }

            if ($this->_lifeTime < 60) {
                $this->_lifeTime = 3600; //one hour
            }

            if ($this->_lifeTime > self::SEESION_MAX_COOKIE_LIFETIME) {
                $this->_lifeTime = self::SEESION_MAX_COOKIE_LIFETIME; // 100 years
            }
        }
        return $this->_lifeTime;
    }
