That's not the implication. It's the norm on this site to include the year of an article in the title (if it's not from the current year, or very recently in the preceding year if in January). There are _plenty_ of links in the top 100-or-so that follow this pattern - hell, I see one from 1997 in the top 30 right now. They can still be interesting/relevant/etc. - but it is worthwhile to read them with the knowledge of when they were published, e.g. if you are evaluating technical approaches.
