This chapter presents an in-depth discussion of the semantics of time indications and proposes a formal time model suited to a variety of computer applications in which temporal databases play a role. The main characteristics of the model are the flexibility inherent to the ability of expressing approximate time indications in a way very close to natural language and the setting of a hierarchical framework, which allows to take into account the most appropriate level of granularity when expressing time indications.
