BrasPag

Olá,

estou tendo dificuldades para fazer um SOAP;

Bem, o q estou fazendo é:

$parametros = new stdClass;
$parametros->request = new stdClass;
$parametros->request->MerchantId = '';
$parametros->request->RequestId = preg_replace('/[{}]/', '', com_create_guid());
$parametros->request->OrderId = 1234;
$parametros->request->ServiceTax = 0;
$parametros->request->CardHolder = 'TESTE';
$parametros->request->CustomerName = 'TESTE';
$parametros->request->TransactionAmount = 100;
$parametros->request->PaymentMethodCode = 18;
$parametros->request->CardNumber = '';
$parametros->request->CardExpirationDate = '';
$parametros->request->CardSecurityCode = '';
$parametros->request->InstallmentCount = '';
$parametros->request->PaymentType = '';
$parametros->request->Cpf = '';
$parametros->request->CurrencyType = '';
$parametros->request->MerchantLocalDate = date('d/m/Y H:i:s');
$parametros->request->BuyerEmail = '';

// OBS: todos os parametros foram preenchidos, conforme o manual da própria BrasPag. Aqui eu os deixei em branco por questões de segurança

$braspag = new SoapClient('https://homologacao.pagador.com.br/pagadorV15/transaction/pagadortransaction.asmx?WSDL', array('trace' => 1, 'exceptions' => 0));
$retorno = $braspag->AuthorizeTransaction($parametros);

O retorno que tenho é:

SoapFault::__set_state(array(
'message' => 'System.Web.Services.Protocols.SoapException: Server was unable to read request. ---> System.InvalidOperationException: There is an error in XML document (2, 952). ---> System.FormatException: The string \'2008-07-29 02:50:43\' is not a valid AllXsd value.

'string' => '',
'code' => 0,

// ......
));

Pergunta: como eu devo enviar esta data? Ja tentei de várias formas e em nenhuma obtive sucesso.
