Dallas semiconductor makes a similar device called a SmartWatch and I know that
its timing is completely independent of the host.
 
I'm sure that the SMT version is independed as well because:
 It will work in an IBM PC as well as an Apple. PC's run at a wide variety of
  CPU clock speeds.
 It plugs into a standard ROM socket with no other connections. The system
  clock or CPU clock isn't available at the ROM socket in an Apple or a PC.
