Google Search Results Rich Snippet With Asked X Years/Months Ago

I am not sure if this is a new snippet, but I don't think I've seen it before where Google shows how many years ago the question was specifically asked in this format. Bhumika Kateliya shared on Twitter an example of this and I was able to replicate a similar one in Google's search results.
