 * Frame timers can also be assumed to be firing at the same time on 
 * different nodes (i.e. global time is being used)
 * Default implementation of this cheats and uses simTime() to calculate
 * the global time points, but eventually this could be implemented using 
 * the standard timers and a proper global time implementation */
