# C# Sharp Exercises: Add millisecond to a given date

## C# Sharp DateTime: Exercise-12 with Solution

Write C# Sharp Program to add one millisecond and 2.5 milliseconds to a given date value and display each new value and the difference between it and the original value.

Note: The difference is displayed both as a time span and as a number of ticks and one millisecond equals 10,000 ticks.

Sample Solution:-

C# Sharp Code:

``````using System;

public class Example12
{
public static void Main()
{
string dateFormat = "MM/dd/yyyy hh:mm:ss.fffffff";
DateTime date1 = new DateTime(2016, 8, 16, 16, 0, 0);
Console.WriteLine("Original date: {0} ({1:N0} ticks)\n",
date1.ToString(dateFormat), date1.Ticks);

Console.WriteLine("Second date:   {0} ({1:N0} ticks)",
date2.ToString(dateFormat), date2.Ticks);
Console.WriteLine("Difference between dates: {0} ({1:N0} ticks)\n",
date2 - date1, date2.Ticks - date1.Ticks);

Console.WriteLine("Third date:    {0} ({1:N0} ticks)",
date3.ToString(dateFormat), date3.Ticks);
Console.WriteLine("Difference between dates: {0} ({1:N0} ticks)",
date3 - date1, date3.Ticks - date1.Ticks);

}
}
```
```

Sample Output:

```Original date: 08/16/2016 04:00:00.0000000 (636,069,600,000,000,000 ticks)

Second date:   08/16/2016 04:00:00.0010000 (636,069,600,000,010,000 ticks)
Difference between dates: 00:00:00.0010000 (10,000 ticks)

Third date:    08/16/2016 04:00:00.0030000 (636,069,600,000,030,000 ticks)
Difference between dates: 00:00:00.0030000 (30,000 ticks)
```
