Event Composition in Time-dependent Distributed Systems ppt

... and end- point thus associating an interval with the composite event instead of using the timestamp of the terminating event. Then we can provide composition operators that allow for interval relations ... time and introduce the concept of accuracy inter- vals. We define abstract interfaces for local as well as glo- bal clock readings used for timestamping events. If we are merely inter...
