advice for clock settings

Dear all,

I'd appreciate some advice on how to configure the bochsrc
clock setting.  This is what I want to do.

I want to run a series of experiments using a workload
running under different conditions.  I've set up a bochs
machine in which this workload can run.  I've installed linux
in this `guest' machine.  If I were running the experiments
on real, physical, hardware, my metric would be wall-clock
time as reported by /usr/bin/time.

What are the bochs clock settings that will most closely
match this?  I am not really concerned by the actual time
taken to run the experiments, that is, I don't care if
a second inside the bochs machine takes 3 seconds to elapse
on the `host'.  What I do want is a metric that allows me
to compare different runs using the times reported inside
the machine.  (As I understand it, clock set to none will
have time inside the machine run at a rate that depends
on the number of instructions executed, which I don't think
does quite what I want.)

Many thanks,

Ariel Burton
