Techniques such as replication and caching of objects that implement distributed services lead to consistency problems that must be addressed. We explore new consistency protocols based on the notion of object value lifetimes. By keeping track of the lifetimes of the values stored in shared objects (i.e., the time interval that goes from the writing of a value until the latest time when this value is known to be valid), it is possible to check the mutual consistency of a set of related objects cached at a site. Initially, this technique is presented assuming the presence of physical clocks. Later, these clocks are replaced by vector clocks and then by plausible docks. Lifetimes based on such clocks result in weaker consistency but do provide more efficient implementations.
