Our logic, TPTL, employs a novel quantifier construct for referencing time: the &quot;freeze&quot; quantifier binds a variable to the time of the local temporal context. TPTL is both a natural language for specification and a suitable formalism for verification. We present a tableau-based decision procedure and a model-checking algorithm for TPTL. Several generalizations of TPTL are shown to be highly undecidable."}],"status":"public","day":"01","quality_controlled":"1","acknowledgement":"The authors thank Rance Cleaveland, Limor Fix, David Karr, Peter Kopke, Fred Schneider, and Bernhard Steffen for helpful comments.","extern":"1","main_file_link":[{"url":"https://link.springer.com/article/10.1007/s100090050007"}],"volume":2,"alternative_title":["AMAST Series in Computing"],"publication":"Theories and Experiences for Real-Time System Development","editor":[{"last_name":"Rus","full_name":"Rus, Teodor","first_name":"Teodor"},{"last_name":"Rattray","full_name":"Rattray, Charles","first_name":"Charles"}],"date_created":"2018-12-11T12:09:38Z","year":"1994","article_processing_charge":"No","date_published":"1994-01-01T00:00:00Z","language":[{"iso":"eng"}],"author":[{"full_name":"Alur, Rajeev","first_name":"Rajeev","last_name":"Alur"},{"id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger","full_name":"Henzinger, Thomas A","first_name":"Thomas A","orcid":"0000−0002−2985−7724"}],"publist_id":"117","page":"1 - 29","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","publisher":"World Scientific Publishing","series_title":"AMAST Series in Computing","publication_status":"published","_id":"4590","doi":"10.1142/9789812831583_0001","publication_identifier":{"isbn":[" 9789810219239"]},"title":"Real-time system = discrete system + clock variables","month":"01","oa_version":"None","keyword":["real-time systems","clock variables"],"citation":{"ista":"Alur R, Henzinger TA. 1994.Real-time system = discrete system + clock variables.
