    calendar1.set(<your earlier date>);
    calendar2.set(<your current date>);
    long milliseconds1 = calendar1.getTimeInMillis();
    long milliseconds2 = calendar2.getTimeInMillis();
    long diff = milliseconds2 - milliseconds1;
    long diffSeconds = diff / 1000;
    long diffMinutes = diff / (60 * 1000);
    long diffHours = diff / (60 * 60 * 1000);
    long diffDays = diff / (24 * 60 * 60 * 1000);
    System.out.println("\nThe Date Different Example");
    System.out.println("Time in milliseconds: " + diff
 + " milliseconds.");
    System.out.println("Time in seconds: " + diffSeconds
 + " seconds.");
    System.out.println("Time in minutes: " + diffMinutes 
+ " minutes.");
    System.out.println("Time in hours: " + diffHours 
+ " hours.");
    System.out.println("Time in days: " + diffDays 
+ " days.");
  }

Clear Cache When made an Ajax Request?

Best choice is add the timestamp to ajax url.its perfect working

var timestamp=Number(new Date());

var url="YoursUrl? timekey="+timestamp;

     OR

Below code is also working but not gurrente

$.ajax({
    type: "POST",
    async: true,
    url: "/manage/update_position/",
    data: {
        "action": action.
        "model": model,
        "object_id": object_id,
        "position": position
    },
    cache: false,
    dataType: "json",
    success: function(data){
        //[snip]
    }
});
