Not even Google seems to be making use of that capability, if they even have it in the first place. I'm regularly annoyed by results claiming to be from this year, only to find that it's a years-old article with fake metadata.
They are quite good at near content duplicate detection so I imagine it's within their capabilities. Whether they care about recency, maybe not as long as the user metrics say the page is useful. Maybe a fallacy about content recency.
You don't see many geocities style sites nowadays, even though there's many older sites with quality (and original) content. Maybe mobile friendliness plays into that though.
