Below is the function used to compare the two time using java scipt.


function checkTime(startTime, endTime) {
//compare two times are same or not....
if (Date.parse('17/06/2013 ' + endTime) - Date.parse('17/06/2013 ' + startTime) == 0) {
        alert('Both time cannot be same');
        return false;
    }
   else if (Date.parse('17/06/2013 ' + endTime) < Date.parse('17/06/2013 ' + startTime)) {
