I have to validate that is end time greater then start time. and my time formate 'HH:MM' ,24 hour formate

eg. start time = 09:14 and end time 12:15 - valid

and start time = 09:14 and end time 01:15 - not valid

thanks have a nice day

I think a/c to this time it should be validate.i am little confused why are giving me this error end time should be greater then start time.

jquery

 $(document).change(function(){

  var startTime =$('#start_time').val(); // 9:15 Am
  var endTime = $('#end_time').val();    // 1:00 pm

    var startTimeParts = startTime.split(":");
    var endTimeParts = endTime.split(":");

    var startDate = new Date();
    startDate.setHours(startTimeParts[0],startTimeParts[1],0,0);
    var endDate = new Date();
    endDate.setHours(endTimeParts[0],endTimeParts[1],0,0);
    if(endTime != ""){
      if (startDate < endDate){
        $(".endTimeMessage").hide();
        $('#btnSubmit').removeAttr("disabled",true);
        return true;
    }else{
        $(".endTimeMessage").show();
        $(".endTimeMessage").text("End time should be greater then start time");
        $('#btnSubmit').prop('disabled', true);
        return false;
    }
    }

});
