.NET 中最准确的计时器? [英] Most accurate timer in .NET?

问题描述

运行以下(略微伪)代码会产生以下结果.我对计时器的不准确感到震惊(每个 Tick 增加约 14 毫秒).

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

还有更准确的吗?

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:
...

12.9190
13.9331
14.9491
