Hi all, If I remember correctly, Provenir[1] has also a Time representation (with Continuant and ocurrent entities), OPMO[2] can handle time durations and intervals and dcterms[3] can state the instant when something was created. We have a lot of different approaches! As for the example, the given suggestions are great.
