This is actually mentioned in google's documentation - you need datePublished and dateModified: https://developers.google.com/search/docs/data-types/article#non-amp https://developers.google.com/search/docs/data-types/article... Even looking from usability standpoint I think that it is totally okay and even necessary to add 'updated' or 'modified' date. Personally, as a reader I'm relying on article created/updated heavily, if I cannot quickly and easily figure out if article is still relevant and up-to-date I'm usually leaving webpage immediately without even bothering to read.
