Yes: "A vector clock is a data structure used for determining the partial ordering of events in a distributed system and detecting causality violations." -- https://en.wikipedia.org/wiki/Vector_clock https://en.wikipedia.org/wiki/Vector_clock with a modification: "In 2008, Almeida et al. introduced Interval Tree Clocks. This mechanism generalizes Vector Clocks and allows operation in dynamic environments when the identities and number of processes in the computation is not known in advance."
