Weird file dates on PDFs

I wonder, why do various Pathfinder PDFs often have such weird file dates? Lots of times they have random dates from 1970, and now I've noticed that some of the most recent batch have dates even from 1956! It's not really a problem, but it's so weird that I really wonder how that happens.

Maybe Gary got some cheap really old servers...

I also wonder what the books might have looked like if they actually were from 1970, or 1956. (I guess that is what catching up on Mad Men over a span of a few weeks does to you...)

Edit: to make matters even more weird, the APG 2nd printing I just downloaded seems to be from the future, with a 2092 file date...

I see this too on my Mac. The zip file has a recent date, but the PDF produced when unzipped is usually back in the 1970s.

Same here. Many recent files have been dated 2023 or 2038, including 3PP products.

Using Linux with InfoZip.

When we zip up the watermarked PDFs for download, we don't actually set the created or modified dates for the files in the zip, so the weird dates the result of one zipping utility or another filling in random information. Is this actually causing a problem for anyone, or is this a question merely out of curiosity?

It's not a problem for me...until I see it. Then my OCD kicks in and it drives me nuts. Of course, my personal personality defects should not impinge upon the available time for Paizo employees. I'll just have to bear it.

It's just annoying. Sorting my unzipped Paizo files by date is useless, so I have to figure out what the new file is by looking at the output from the unzipper. Paizo's file naming convention doesn't help matters.

None of this is a big deal, though. I have a process now that works for me and I've managed OK so far.

It would be nice to have them dated by release date, to make it easy to check against lists of what is available to see what I have already got. I think that alphabetical sorting by filename accomplishes this already, but I'm not 100% sure.

So no great problem, just a nice-to-have.

For me it's not a problem, it just looks weird and made me wonder. Still, I think it is strange that the files don't have "normal" dates even before they get zipped.

I don't think I could even create a file with a date from 1956 without changing my system time (and it probably couldn't even be set that far back...) or consciously manipulating binary file metadata. Hm.

Given that I rename everything on my RPG Archive drive to a standard format, and due to a disk crash a year ago it has been rebuilt completely over this year, all mine now have a date somewhere in 2010 :)

So just rename everything in the order that you want them sorted, and you ought to be all right!

I use the Winrar option "Extract Here" to unzip quickly, and generally end up with dates at all for Paizo files. That includes PDFs from other publishers for what it's worth, so Ive always assumed it's something caused by the watermarking process.

I find it somewhat annoying as I often sort by date when using Windows Explorer.

Use the Date Modified option. This sorts it by the day you unzipped.

Yes, it's a problem for me, I check the dates when I'm checking to see if I need to update a PDF and in general I like to know when I downloaded something.

The creation dates on downloads from Paizo.com should no longer be random. They should now be the time that the file was watermarked.
