Yet many verification methods are based on the assumption that states are observed at integer time points only. What can we conclude if a real-time system has been shown “correct” for integral observations?\r\n\r\nInteger time verification techniques suffice if the problem of whether all real-numbered behaviors of a system satisfy a property can be reduced to the question of whether the integral observations satisfy a (possibly modified) property. We show that this reduction is possible for a large and important class of systems and properties: the class of systems includes all systems that can be modeled as timed transition systems; the class of properties includes time-bounded invariance and time-bounded response.","lang":"eng"}],"date_published":"1992-01-01T00:00:00Z","extern":"1","publication_status":"published","date_updated":"2022-03-14T09:47:09Z","month":"01","article_processing_charge":"No","day":"01","type":"conference","acknowledgement":"A full version of this paper (including all proofs) is available as a technical report from Cornell University and Stanford University.
