C#转向时间 - 转换错误

Question

我试图将刻度转换为格式化的日期/时间值,但我注意到时间不正确.

在下面的示例中,numberOfTicks1的值小于numberOfTicks2.但是,当我创建它的格式化日期/时间值时,numberOfTicks2比numberOfTicks1少约50s ...

为什么会这样？我应该以不同的方式转换它们吗？

long numberOfTicks1 = 635904556104808905;
long numberOfTicks2 = 635904559203480591;

DateTime myDate1 = new DateTime(numberOfTicks1);
DateTime myDate2 = new DateTime(numberOfTicks2);

Console.WriteLine(myDate1.ToString("dd-MM-yyyy HH:MM:ss.fff"));
Console.WriteLine(myDate2.ToString("dd-MM-yyyy HH:MM:ss.fff"));

// Result
//07-02-2016 15:02:50.480
//07-02-2016 15:02:00.348

**更新**

 YYYY = four-digit year
 MM   = two-digit month (01=January, etc.)
 DD   = two-digit day of month (01 through 31)
 hh   = two digits of hour (00 through 23) (am/pm NOT allowed)
 mm   = two digits of minute (00 through 59)
 ss   = two digits of second (00 through 59)
 s    = one or more digits representing a decimal fraction of a second

我强烈怀疑这是因为你使用MM说明符而不是mm说明符.

Console.WriteLine(myDate1.ToString("dd-MM-yyyy HH:mm:ss.fff"));
Console.WriteLine(myDate2.ToString("dd-MM-yyyy HH:mm:ss.fff"));

真正的结果应该是:

07-02-2016 15:26:50.480
07-02-2016 15:32:00.348
