In distributed real-time systems, to allow the system to have a notion of a global time, its components must have their clocks synchronised, which eventually results in time uncertainties between the components. In other words, an event external to the system may have different occurence times in the various components from which the system is made up. These time uncertainties can cause value uncertainties whenever any two components attempt to measure the same physical variable "at the same time". This paper discusses the type of errors which can be present in any measurement performed in either the time or value domains, and how these errors are related.
