The Spatial Data on the Web Working Group is finalizing the "Time Ontology in OWL" specification:

https://w3c.github.io/sdw/time/

The group intends to request transition to Candidate Recommendation before end of April, and is thus actively looking for feedback on the specification by then.

Abstract:
OWL-Time is an OWL-2 DL ontology of temporal concepts, for describing the temporal properties of resources in the world or described in Web pages. The ontology provides a vocabulary for expressing facts about topological relations among instants and intervals, together with information about durations, and about temporal position including date-time information. Time positions and durations may be expressed using either the conventional (Gregorian) calendar and clock, or using another temporal reference system such as Unix-time, geologic time or different calendars.

A summary of changes from previous versions is available in the spec:

Thanks,
Francois.
