On FreeBSD you could try selecting the "dummy" timecounter.
I think this will produce a counter that steps in a rather
clunky way. Something like:
sysctl kern.timecounter.hardware=dummy
should probably work. (Running "sysctl kern.timecounter" will
output various information about the available timecounters.)
