Hi
As per the following discussion

gettingsystemperfo
rmance.001.txt
clock_get_uptime gives system up time in CPU cycles.
Is there a way in kernel or IOKit to know the CPU cycles per second?
A little digging through xnu source should show where this is coming
from:
pbg3:ksh$ sysctl hw.cpufrequency
hw.cpufrequency = 300000000
