The Parisi scheme for equilibrium and the corresponding slow dynamics with\nmultithermalization - same temperature common to all observables, different\ntemperatures only possible at widely separated timescales -- imply one another.\nConsistency requires that two systems brought into infinitesimal coupling be\nable to rearrange their timescales in order that all their temperatures match:\nthis time reorganisation is only possible because the systems have a set of\ntime-reparametrization invariances, that are thus seen to be an essential\ncomponent of the scenario.\n
