Have seen a few times before the concept, but still always remember, simply write it down, easy to see in the future ~The so-called clock time is also called the wall clock time, it is the total number of clocks that the process is running, and its value is related to how many processes are running concurrently in the system, although it is generally measured when there are no other activities in the system when discussing clock time.User CPU Time: Is
