Hi,
In Pages that HTML code is used:
<meta property="article:published_time" content="2024-06-23 16:50:13">
<meta property="article:modified_time" content="2025-06-27 07:36:58">
it was added a few month ago. So yes, Google does recognize and use them to a certain extent. Specifically for dates, Google's algorithms consider various signals to determine the publication and modification dates of an article.
Even who created it is also there:
<meta property="article:author" content="Paul">
Preview your page sourecode and you will see it too :]
