Import PDF lose creation date

Sadly, it appears creation date of a Pdf file is modified while imported in DT.

Is an another way to import can help me keep this (essential) information?
Or I need to manually input creation date
Or maybe something to improve in DT

DEVONthink uses always the file’s creation/modification date when importing, the result should be consistent to the Finder.

I guess they’re talking about the metadata here, as stored inside the PDF. There was another thread about this topic recently, iirc.

Edit : I don’t know if it is metadata embedded or finder metadata but I’m going to look at this potential thread,

I’m aware of this thread but I still wonder whether DEVONthink should always use the internal dates instead of the file dates or not. So far only the creation date of emails is changed in such a way when importing.

the result should be consistent to the Finder.

I think this is the key takeaway.

I’m not sure either. It seems that some people prefer the DT creation date to be identical to the PDF creation date (metadata). Maybe a script in the batch section or in smart rule section that copies the PDF creation date to the DT creation date could be a compromise?

If you have a PDF with a discrepancy between the metadata date and the file date, please ZIP it and attach it to a support ticket. Thanks!

Done!

TY!

The next release will support this by enabling a hidden preference.

Apologies for resurrecting this old thread – I’m just wondering what this hidden preference is called? Couldn’t find it in the documentation, and I can’t find the release notes for DT 3 online.

From the 3.9.9 manual:

UsePDFDocumentDates: Use the PDF’s internal metadata dates instead of the filesystem dates when importing and setting creation and modification dates.

(the Handbooks and Extras page only links to the 4.0beta1 manual, but you can still fetch it here)

It’s not listed in the 4.0beta1 manual. Don’t know if if was removed or it’s just an oversight.

Tx. Since I had compressed my DT installation, I didn’t have access to the documentation anymore…

It seems to be called UseDocumentDates now. And also missing from the documentation.

It is now a real preference, see. Settings > File > Import

And documented :slight_smile:

Thank you for this implementation !
