1.This function calculates the difference between two jiffies values, and then provides the result to the user through a user-space pointer.
这个函数会计算这两个jiffies值之间的差值，然后通过一个用户空间指针将结果提供给用户。
2.Even the jiffies (small packets of kernel time for timing interrupts) are not altered and this lets you debug the Interrupt Service Routine.
此时连jiffies（用来对中断进行计时的内核时钟滴答数）都不会改变，这样就可以对ISR进行调试了。
3.Although timers operate on the granularity of jiffies, hrtimers operate at the granularity of nanoseconds.
尽管计时器在jiffies粒度上运行，hrtimers在纳秒粒度上运行。
4.For more information about jiffies, see the sidebar, " Kernel jiffies. "
（有关jiffies的更多信息，请参看侧栏“Kerneljiffies”）。
5.This API permits the construction of timers that operate in the jiffies domain (minimum 4ms time-out).
这个API允许构造在jiffies域（最低4ms超时）中运行的计时器。
6.In Listing 1, two functions are provided for jiffies monitoring.
在清单1中，我们为进行jiffies监视提供了两个函数。
7.A new jiffy counter called jiffies_64 has been introduced to avoid the rapid overflow of the jiffy variable because of the HZ value change.
引入了一个叫做jiffies_64的瞬间计算器，以避免由于HZ值的变化而引起瞬间变量的迅速溢出。
8.The tick rate (jiffies's least significant bit) is configurable, but in a recent 2. 6 kernel for x86, a tick equals 4ms (250Hz).
滴答速率（jiffies的最不重要的位）可以配置，但在最近针对x86的2.6内核中，一次滴答等于4ms（250Hz）。
9.The first thing you'll notice is that time is represented not in jiffies but in a special data type called ktime.
应该注意的第一点是：时间不是用jiffies表示的，而是以一种名为ktime的特殊数据类型表示。
