Distributed Systems Foundations Physical Clock Synchronization CS171 2 Physical Clocks • It is impossible to guarantee that crystals in different computers all run at exactly the same frequency. This difference in time values is clock skew. • “Exact” time was computed by astronomers – The difference between two transits of the sun is termed a

LNCS 4354 – QuickCheck Testing for Fun and Profit QuickCheck Testing for Fun and Profit John Hughes Chalmers University of Technology, S-41296 Gothenburg, Sweden 1 Introduction One of the nice things about purely functional languages is that functions often satisfy simple properties, and enjoy simple algebraic relationships. Indeed, if the functions of an API satisfy
