Summary
The current concept of time is reviewed with the aim of underlining its relation with the evolution of dynamical systems. It is shown that the index ordering the values of a variable in a sequence generated by a nonlinear mapping gives a different, system-dependent, time measure than the phase of a simple periodic motion. Some ergodicity problems in the construction of invariant distributions for iterated mappings are indicated.
