 public int GetTimeDifference(DateTime one, DateTime two)

      {

          if (DateTime.Compare(one, two) <= 0)

          {

              TimeSpan tspan = one.Subtract(two);

              Console.WriteLine(tspan.TotalDays);

              Console.WriteLine(tspan.TotalHours);

              Console.WriteLine(tspan.TotalMinutes);

              Console.WriteLine(tspan.TotalSeconds);

              Console.WriteLine(tspan.TotalMilliseconds);

          }

          return 1;
