%B Communicating Process Architectures 2009
%X As part of the CoSMoS project, we have implemented a variety
   of
complex systems simulations using occam\-pi. occam\-pi is
   unusual in
that it provides built\-in support for
   synchronisation against a
real\-time clock, but simulations
   generally need to run faster or
slower than real time.  We
   describe the idea of a \[dq]clock\[dq] \-\- a
   new
synchronisation primitive for process\-oriented
   programming, similar to
a barrier but extended with a sense
   of time. Clocks can be used to
provide simulated time in a
   complex systems simulation, and can also
be used to
   implement efficient phase synchronisation for
   controlling
access to shared resources.
