title: Apex Scheduler Salesforce, execution error
body: <p>I have a big problem with apex scheduler.
  I've always get this error message, when I try to execute the scheduler:
  "Global type must be contained inside of a global class"</p>
  
  <p>This is the code example:<br>
      <code>global class updateData implements Schedulable {        global void execute (SchedulableContext SC) {        DataContact dContact = new DataContact();        dContact.UpdateContact();        }        }</code></p>
  
  <p>Thanks!</p>
