utime.ticks_diff(old, new) 计算两次调用 ticks_ms(), ticks_us(), 或 ticks_cpu()之间的时间。因为这些函数的计数值可能会回绕,所以不能直接相减,需要使用 ticks_diff() 函数。“旧” 时间需要在 “新” 时间之前,否则结果无法确定。这个函数不要用在计算很长的时间 (因为 ticks_*() 函数会回绕,通常...

Ticks的差，只是⼀个较⼤数的整数倍。例如在我的机器上，这个差最⼩是10.114ms。所以，如果我⽤DateTime.Now来计算时间差，那么就⽆法精确到10ms以内。后来发现 ASP.NET的TRACE的精度很⾼，⽤Reflector看它的实现，发现了它是使⽤这两个⽅法的：我⾃⼰了按照这个写了个类，代码如下:using ...

1 ms = 10,000 clock ticks on a Windows system, as described inDateTime.Ticks Property. For example, 5 minutes becomes 5 × 60 × 1000 × 10000 = 3,000,000,000 clock ticks. In the following section, "All versions" refers to Windows 7, including future iterations, and Windows ...
