Abstract
A method of performing clock synchronization between two apparatuses includes storing, in a first apparatus, information representing synchronization accuracy required by at least one function of the apparatus; carrying out, by the first apparatus, a service discovery procedure with a second apparatus, and receiving clock information from the second apparatus during the service discovery procedure; determining, by the first apparatus on the basis of the received clock information and said stored information, whether or not synchronization accuracy is sufficient for the at least one function; and upon determining that the synchronization accuracy is sufficient for the at least one function, synchronizing a clock of the first apparatus with a clock of the second apparatus.
