It seems to be important to be albe to know when a dcument was signed. Veverve (talk) 10:52, 10 October 2020 (UTC)[reply]

Oppose why not simply use point in time (P585)? Or even better use the date it was signed by each party and combine point in time (P585) with qualifier signatory (P1891), similar to here. Some treaties/documents are not signed by all participants on the same date. --Hannes Röst (talk) 18:30, 10 October 2020 (UTC)[reply]
Oppose Using signatory (P1891) with either point in time (P585) or start time (P580) works better given that different signatories sign often on different dates. ChristianKl ❪✉❫ 17:54, 12 October 2020 (UTC)[reply]
Oppose signatory (P1891) with point in time (P585) should be sufficient. --Tinker Bell ★ ♥ 06:00, 16 October 2020 (UTC)[reply]
