[erlang-questions] wall_clock, runtime - what is the difference?

[Paul Nelson]

I don't know for sure, but I can make an educated guess. Since erlang is not
guaranteed to have 100% of your CPU time, runtime would be the actual amount
of processing time used by erlang. "wall_clock" time is simply recording the
actual time the process started and the actual time the process ended and
giving you the difference in "real time" (i.e. time as reported by a clock
on the wall).

That's my educated guess, anyway. :-)
