According to http://www.lisp.org/HyperSpec/Body/fun_get-internal-run-time.html

Description:

Returns as an integer the current run time in internal time units. The precise meaning of this quantity is implementation-defined; it may measure real time, run time, CPU cycles, or some other quantity. The intent is that the difference between the values of two calls to this function be the amount of time between the two calls during which computational effort was expended on behalf of the executing program.

How can I determine "what" GET-INTERNAL-RUN-TIME measures?



Thanks in advance
