Although currently a tick is 100 nanoseconds, it is best not to rely on this as an absolute. Rather, use 'TimeSpan.TicksPerSecond' (or any of the other TicksPerXxx member values)

虽然目前一个滴答是 100 纳秒，但最好不要将其作为绝对值。而是使用“ TimeSpan.TicksPerSecond”（或任何其他 TicksPerXxx 成员值）

The tickis the unit of granularity for the .NET DateTimeand TimeSpanvalue types.

的蜱是粒度为.NET的单元的DateTime和时间跨度值类型。

It has the following common conversions:

它有以下常见的转换：

1 tick = 100 nanoseconds
       = 0.1 microseconds
       = 0.0001 milliseconds
       = 0.0000001 seconds

To quote MSDN:

引用MSDN：

The smallest unitof time is the tick, which is equal to 100 nanoseconds.

的最小单位的时间刻度，这是等于100纳秒。

Note that, although the theoretical resolution of DateTime.Now is quite high, the resolution - ie how often it is updated - it quite a bit lower.

请注意，虽然 DateTime.Now 的理论分辨率相当高，但分辨率（即更新频率）却低了很多。

Apparently, on modern systems, DateTime.Now has a resolution of 10 milliseconds... See msdn.microsoft.com/en-us/library/system.datetime.now.aspx

显然，在现代系统上，DateTime.Now 的分辨率为 10 毫秒...请参阅msdn.microsoft.com/en-us/library/system.datetime.now.aspx
