The mechanism is exactly as in any other x86 based hardware, with the 
exception of not being persistant across power outage. Please look at 
the hwclock command, this is what I see on my WRAP, which uses the 
original ntpd stuff, which is a bit bigger, but that does not bother me.

gatekeeper# hwclock ; date;
Wed Feb 10 17:04:04 2010  0.000000 seconds
Wed Feb 10 17:04:03 UTC 2010

so my hwclock runs a bit faster than the system clock, which is kept 
updated by ntp, let's just adjust it

gatekeeper# hwclock -w
gatekeeper# hwclock ; date;
Wed Feb 10 17:05:55 2010  0.000000 seconds
Wed Feb 10 17:05:55 UTC 2010

here is the ntp status

gatekeeper# ntpq -np
      remote           refid      st t when poll reach   delay   offset 
  jitter
==============================================================================
*195.141.190.190 212.161.179.138  2 u   54   64   37    0.393   -9.413 
  4.027

cheers

Erich
