I share an interest in this topic, and have come up with a partial set of coping strategies. - I open the popup for the 'SEOInfo' firefox plugin which displays metadata from the page (JSON-LD, microdata, and a catch-all "other meta" field often show created/modified timestamps for the current page) - A page may give a date but if the page has a whiff of marketing vibe about it and that date is very recent and not in the url I am immediately suspicious of the date it gives. - I click over to archive sites (Internet Archive/wayback machine, archive.today). I'll often bookmark a good early capture from one of these next to the actual page for the sole reason that the capture has some semblance of a date, even if it's not close to the actual published date. I want that simply because I like to order links by date and so I need some date to use for that. - Academic papers are especially frustrating here. Some have a date prominently in the pdf but most don't. This is apparently an artifact of a process whereby papers often simply don't have a definitive date. The authors worked on it over the course of a year or more, so many differing versions are floating around. For these I google the title and can often get an arxiv preprint page with a submission date, or journal publications with a submission date (though these often only give a month or a year). - There is a lot of good stuff on a stackoverflow page but what's the "date" of that page? A question could have been asked a decade ago and have answers running from that day to today. I really like the wayback machine for these. I can start with an early version of the page and click forward through time, bookmarking when I stop. Then if I pick it up again later, I can resume from the bookmark and continue forward through time from there. - Quora pages are especially frustrating because they won't give the date the question was asked; just the answers. And you can't do the wayback machine thing I described above for stackoverflow because Quora has blocked internet archive. For these reasons I dread trying to do anything with quora pages. What I'd really wish for is some way browsers can get create/modify dates for any page, so the user doesn't need to hunt for it and plugins can do stuff with it. For example I'd love a plugin that could order the tabs in a window by, say, modification date. The workflow I have in mind is: open search results into tabs. Make the browser order the tabs by date for you without manual labor. Then you can read through your search results in chronological order. Save the set. Restore it a week or a year later. Click "reorder" again to account for pages that have received updates. Now your tabs are in chronological order again. I would gladly pay for this capability!
