 * @format defaults to 12 hour format,
 *   or if langSet is indicated defaults to most appropriate format for that langSet
 *   $("#mydiv").clock(); >> will have 12 hour format
 *   $("#mydiv").clock({"langSet":"it"}); >> will have 24 hour format
 *   $("#mydiv").clock({"langSet":"en"}); >> will have 12 hour format 
 *   $("#mydiv").clock({"langSet":"en","format":"24"}); >> will have military style 24 hour format
 *   $("#mydiv").clock({"calendar":true}); >> will include the date with the time, and will update the date at midnight
