Time and state are two key notions used in a conventional OS. However, these notions cannot be used in the same manner in a distributed system because it contains several computer systems, each with its own clock and memory, that communicate through messages that incur unpredictable communication delays. This chapter discusses practical alternatives to the traditional notions of time and state. These alternative notions are used in the design of distributed control algorithms and recovery scheme
