Wall time is thus different from cpu time which measures only the time during which the processor is actively working on a certain task.
The user cpu time and system cpu time are pretty much as you said the amount of time spent in user code and the amount of time spent in kernel code.
The number of microprocessor clock cycle s per second of wall time depends on the microprocessor s clock speed.
The reference to a wall clock is how the term originally got its name wall time differs from time as measured by counting microprocessor clock pulses or cycles.
The units are seconds and subseconds which might be microseconds or nanoseconds.
