Title
Body
When calculating the millisecond difference between two DateTime objects I always seem to get a number returned where the decimal part of the number is the same as the integer component of the number. For example: 1235.1235 Why does this happen? Am I doing something wrong? Is this a quirk of the language or a limitation of the DateTime granularity or something? This can be demonstrated using the following code: DateTime then = DateTime.Now; Thread.Sleep(1234); DateTime now = DateTime.Now; TimeSpan taken = now - then; string result = taken.TotalMilliseconds.ToString(CultureInfo.InvariantCulture); //result = "1235.1235" As commented by CodesInChaos: DateTime` isn't accurate to this level of precision: see C# DateTime.Now precision However - that doesn't quite explain this behavior.
