Answer 1

Error you getting is becasue you don't have a function in your main.js file called "getServerDate".

Make sure you have it defined correctly as follows in your main.js file:

Parse.Cloud.define("getServerDate", function(request,response){

//Your javascript logic comes here and return the server date to the response

});
