   I was recently faced with the same problem. The Answer
There is not ^*%&^%$^%$ way!

My solution to this problem was to recomplie the program on a Amiga500
and time the part I wanted using the hardware CIA timers (1.3us per tick)

I was also informed another person in the same boat did his timing on
a Mac.

                   I really hate this damm machine,
                    I wish that they would sell it.
                     It never does quite what I want,
                      Only what I tell it.
