Hierarchical scheduling frameworks (HSFs) provide means for composing complex real-time systems from welldefined subsystems. This paper describes an approach to provide hierarchically scheduled real-time applications with virtual event timers, motivated by the need for integrating priority processing applications in an HSF. Specifically, the paper proposes a technique to minimize the overhead of event handling in HSFs and outlines a simple implementation.
