C# Question

Most accurate timer in .NET?

Running the following (slightly pseudo)code produces the following results. Im shocked at how innacurate the timer is (gains ~14ms each

Tick
).

Is there anything more accurate out there?

void Main()
{
var timer = new System.Threading.Timer(TimerCallback, null, 0, 1000);
}

void TimerCallback(object state)
{
Debug.WriteLine(DateTime.Now.ToString("ss.ffff"));
}

Sample Output:
...
11.9109
12.9190
13.9331
14.9491
15.9632
16.9752
17.9893
19.0043
20.0164
21.0305
22.0445
23.0586
24.0726
25.0867
26.1008
27.1148
28.1289
29.1429
30.1570
31.1710
32.1851
