A join is exact: Wargaming lists it with the roster. A departure or a change of position is noticed when the roster is next refreshed, so it is shown with the window it happened in — this clan has been followed since 15 Oct 2026. Changes of position are known only from when this site began recording them; earlier ones are not shown. Where a player’s own membership history has been fetched, its exact dates are shown instead, including earlier ones.
