Description:
------------
When using the PHP SOAP client to send over a dateTime object; the client correctly turns a unix timestamp into the appropriate XML dateTime object.

When using the PHP SOAP ext to write a SOAP service; the value is not decoded.

Using the WSDL available via:

  http://ws1.api.re2.yahoo.com/ws/soap-demo/full-php.wsdl

a PHP5 SOAP client will send a request containing a dateTime encoded entity:

  <ns1:dtval>2005-02-28T12:40:51-0800</ns1:dtval>

based on calling the function with a Unix timestamp:

  $client->dateInfo(array( 'dtval' => time() ));



However, a PHP5 SOAP server receiving the request:

  <ns1:dtval>2005-02-28T12:40:51-0800</ns1:dtval>

does not decode the dateTime object into a time_t.  Instead, it passes the raw value to the service method.



Reproduce code:
---------------
<?php
$WSDL = "http://ws1.api.re2.yahoo.com/ws/soap-demo/full-php.wsdl";

function dateInfo( $req )
{
    $dtval = $req->dtval;
    error_log("Returned $dtval", 0);
    return ( array( 'dateString' => "no ctime function",
                    'dateSeconds' => $dtval ));
}

ini_set("soap.wsdl_cache_enabled", "0"); // Disable WSDL caching
$server = new SoapServer( $WSDL );
$server->addFunction("dateInfo");         # 2
$server->handle();
?>


Expected result:
----------------
When using a SOAP client that hits the above script; I would expect the error log to contain:

[...] [error] Returned 1234567890

instead, it's returning:

[...] [error] Returned 2005-02-28T19:22:24Z
