Furthermore, in order to avoid clock skew familiar in high-speed sequential logic circuits, negative clock skew system is used in clock routeway and buffers are placed in clock-tree.

此外，为了避免高速时序电路中常见的时钟偏差，时钟通道采用负时钟偏差系统，并在时钟树中放置了缓冲器。

If this value is negative, the clock time is set back at the start of daylight saving time and advanced at the end.

如果此值为负值，则时钟时间会在夏时制开始时向后调整，而在夏时制结束时向前调整。

First of all, negative time should not bother anybody; t=0 is when I set the clock, I measured time forward, but yesterday would be t = -1 day, right?

首先,负的时间对我们不存在任何干扰,t=0使我们设定的初始时间,我是用顺序计时,所以昨天就可以记为-1天,对吗

They successfully employed this approach during the primary season, running negative ads around the clock in key states.
