Sure! But a model of clocks can appear in a mathematical theory. Such a model of "clocks" is a family of functions from R to R^R (the set of functions from R to R) defined by : f_{\delta}: t_0 -> [ t -> t + t_0 + \delta ] For a given \delta > 0 f_{\delta} is a function taking the "initial value of the clock" as an argument and returning a family of clocks "running at the same rate" F_{t_0}, which are function from R to R. Values showed by a specific clock F = F_{t_0} can be obtained by evaluation of F(0), F(F(0)), F(F(F(0))), etc. This can actually be implemented in a program for, for instance, illustrate the Einstein-Poincaré synchronization procedure. Using a "pure" functional language could be nice. You could try. > [snip boring lie] > piece of shit Nice signature Wozniak! Again, unfortunately in the middle of your post!
