            Console.WriteLine("Currnt date time is: " + dt1.ToString());
            
            //another DateTime object to store the updated date time
            //adding 30 hours
            DateTime dt2 = dt1.AddHours(30);
            //updated date time is

            dt2 = dt1.AddHours(48);
            //updated date time is 
            Console.WriteLine("Updated date time is: " + dt2.ToString());
