Getting Task Elapsed Times

[joofung@iss.nus.sg (Wong Joo Fung)]

Hi folks:

Has anyone used the (get-internal-run-time) function in MCL to calculate the
elapsed times for performing a task?

The context is that I need to determine the time taken to issue a pen gesture,
with an accuracy of up to 10 milliseconds, if possible.  Although the
get-internal-run-time variable says that (get-internal-run-time) is accurate
to 1000 milliseconds, would this accuracy still hold if GC is *always* turned
on?

Any clarification would be much appreciated.

(I was actually reading IM Vol 7 -- extended time manager and all -- until I
had the sense of mind to check up CLTL2).  :-)

Thanks and regards,
