Abstract :
The paper addresses the challenges and opportunities of instrumenting pervasive computing systems with a logical clock, aware of the quality of synchronization with respect to a time reference. Pervasive computing systems are: i) mobile; ii) dynamic; and iii) composed of a large number of distributed components; in systems with these characteristics the availability of a "smart" clock that is: i) capable to use different mechanisms for the synchronization with the global distributed time reference; and ii) aware of the current quality of synchronization with such time reference, can be very useful in order to build dependable middleware services and applications
