Yes it set at default value
sysctl kern.clockrate
kern.clockrate: { hz = 100, tick = 10000, profhz = 1024, stathz = 128 }

but in freebsd 4.5, 5.3 in my network this set in HZ 100 too, and i
have not this problem on those computers

FreeBSD 4.5
sysctl kern.clockrate
kern.clockrate: { hz = 100, tick = 10000, tickadj = 5, profhz = 1024, stathz = 128 }
router# uname -a
FreeBSD _______ 4.5-RELEASE FreeBSD 4.5-RELEASE #5: Wed Dec  8 16:36:11 EET 2004     _________:/usr/src/sys/compile/DSL  i386

kern.clockrate: { hz = 100, tick = 10000, profhz = 1024, stathz = 128 }
