Zabbix serviceGet service Time

[imjules]

Hello I have some services and I want to get their "uptime" with the API.
I have already the SLA with this code:

$apiT = new ZabbixApi($apiurl, $user, $passwd);
    $apiT->setDefaultParams(array(
        'output' => 'extend',
        'serviceids' => $idT,
        'intervals' => array(
            'from' => time(),
            'to' => time()
        )
    ));
    $slaT = $apiT->serviceGetTimes();
    $arrayT = json_encode($slaT, true);
    $jsonArrT = json_decode($arrayT, true);
    
    $StringDataT = $jsonArrT[62]['sla'][0]['sla']; 

But now I want to get the Service Time but I can't find a solution...
