Which timestamp is relevant on the body of a Wikipedia article that has been maintained for 15 years, with edits ranging from entire new sections being written to minor corrections of grammatical errors.

At the very least you should provide the inital publish date and last update.

Doesn't provide an edit history in the article, though.
