VMware 3.2 on Linux, NetBSD 4beta. Full dmesg.boot is below.

     # sysctl kern.timecounter
     kern.timecounter.choice = clockinterrupt(q=0, f=100 Hz) TSC(q=-100, 
f=1813623160 Hz) piixpm0(q=1000, f=3579545 Hz) i8254(q=100, f=1193182 Hz) 
dummy(q=-1000000, f=1000000 Hz)
     # sysctl -w kern.timecounter.hardware=i8254
     kern.timecounter.hardware: piixpm0 -> i8254

This makes "sleep 1" consistent with system time.

     # while :
     > do
     > date
     > sleep 1
     > done

     #

With piixpm0, "sleep 1" is correct but system time is 30+ times
too slow.

     # while :
     > do
     > date
     > sleep 1
     > done
