Is it a Google bug if the News tab time stamp shows the real time published?
JOHN MEULLER (Webmaster Analyst from Google):
So what you might be seeing there is in the organic search results, we sometimes show the date in the snippet. And that date is algorithmically generated partially based on the content you have there and partially based on other factors. And that’s not something that would be affecting the ranking of the page. That’s essentially, from our point of view, a part of the snippet. It’s something we pulled out from your page or kind of inferred from your page. And we’re showing that as a part of the snippet. So it’s not something that we would say is a ranking factor or something that you need to optimize for or something that you need to tweak like that. That’s essentially just a part of the text that we show in the description there.
