%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.
