那么你的时钟在墙上显示。
不需要任何工具，功能或其他提供
你的C程序的这些信息，特定于系统的扩展名

术语挂钟时间是指活动
所花费的时间，并且暗示了对此类活动进行计时的方法：在活动开始时查看
挂钟，再看一下活动结束，
计算两次之间的差异。
我们使用这个术语与cpu time对比，后者衡量已经过去的时间
活动所用的时间，不包括计算机执行该活动任务的所有时间（即数据输入时间等）。

Well its the time that your clock on the wall shows.
There need not be any tool, function or else that provides
your C programs with this information, system specific extensions make
make this available.

I don''t know of any standardized meaning for it, but
I''d guess it means ''local time''.

Nope.

Perhaps if you give context, we could figure out
what the poster(s) meant.

The term "Wall clock time" refers to the elapsed time that an activity
takes, and alludes to the method of timing such an activity: look at the
wall clock when the activity starts, look again when the activity ends,
compute the difference between the two times.
We use this term in contrast to "cpu time", which measures the elapsed
time that an activity takes, excluding all the time the computer is not
performing tasks for that activity (i.e. "data entry" time, etc.).
