You can check in Firebug name of the files from which error is coming. 
Then go to that file and include the js whose variables are coming undefined.
For example:

require([

    'jquery',

    'mage/mage',

    'mage/calendar'

], function($){

  //code here

});

The error you mentioned is coming because js used for variables timepicker and dialog is not included in that page.
