.net - 测量耗时会计日光节约

Question

我有一些代码可以测量某些操作花费的时间。如果夏令时在操作过程中生效，我会得到不准确的数据。

比如我在做

DateTime startAt = DateTime.Now;
DoOperation(); //day light saving takes effect in the middle
int seconds = (DateTime.Now - startAt).TotalSeconds;
//second has wrong seconds

有没有办法衡量这一点？

谢谢

改用 StopWatch 类...例如

var stopWatch = new StopWatch();
stopWatch.Start();
//code here
stopWatch.Stop()
Console.WriteLine("elapsed millisconds " + stopwatch.ElapsedMilliseconds);
