This was my attempt to use the GeteBayOfficialTime from the Trading API... I simply copied and pasted what worked from this site: https://developer.ebay.com/DevZone/build-test/test-tool/default.aspx and yet I'm getting a failure code... any ideas? It just so happens the GeteBayOfficialTime isn't on the top error codes list http://developer.ebay.com/DevZone/XML/docs/Reference/ebay/Errors/errorsByCall.html, my error code is 10012

This is the code:

 function myFunction() {
   var url = "https://api.sandbox.ebay.com/ws/api.dll";
   var request = HtmlService.createHtmlOutputFromFile('xml').getContent();  
   var params = {
     method:'get',
     payload:request,
     headers: {
       "X-EBAY-API-COMPATIBILITY-LEVEL":851,
       "X-EBAY-API-DEV-NAME":"replace",
       "X-EBAY-API-APP-NAME":"replace",
       "X-EBAY-API-CERT-NAME":"replace",
       "X-EBAY-API-SITEID" :0,
       "X-EBAY-API-CALL-NAME":"GeteBayOfficialTime"
     }
   }  
   var response = UrlFetchApp.fetch(url, params).getContentText();    
   //var object = xmlToJson(response);
   Logger.log(response);
 }

This is the XML file that the 3rd line from the above code refers to, again, everything is copied and pasted:
