We present a new architecture for a clock synchronization protocol based on multi-cast communication. The protocol implements the gradual tuning of the clocks, in order to automatically compensate the {\em systematic} drift and increase the time between re-synchronizations. Hosts participating to the same service are grouped into a cohort: the protocol self-stabilizes into an optimal routine where all members of a cohort are periodically synchronized with the same messages. New members dynamically joining the cohort perturb this routine, that is spontaneously and eventually restored.
