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.
