    public string CalculateTimeDifference(DateTime startDate, DateTime endDate)
    {
        int mins = 0; int secs = 0; int days = 0; int hours = 0;
        string final = string.Empty;
       
        if (endDate > startDate)
        {
            days = (endDate - startDate).Days;
            hours = (endDate - startDate).Hours;

            mins = (endDate - startDate).Minutes;
            secs = (endDate - startDate).Seconds;
            final = string.Format("{0} days {1} : {2} : {3} ",  days.ToString(), hours.ToString(),  mins.ToString().PadLeft(2, '0'), secs.ToString().PadLeft(2, '0'));
        }
        else
        {
            final = "Expired";
        }
        return final;
