I don't think this has to do with the issue I mentioned. Google has gives a date for these articles when you do a regular search. As I mentioned, these are mostly around 2011. Again, these dates are coming from Google, not the site. If I do a time range that includes 2011 in it, even a time range that includes the entire existence of the internet (1900 to 2022), all of the sites except one disappear. It's not a matter of Google getting a date wrong, it's a matter of Google not displaying hits that it should be displaying per the data in its own system.
