Hi @hhrutter

We're facing an issue where pdf validation is unsuccessful due to the following validation error pdfcpu: validateDateObject: <D:> invalid date

We're able to open and view these files successfully in Mac Preview and Acrobat Reader on Mac OS Ventura and Windows 7/10 respectively using the latest commit (v0.4.3-0.20230731072739-a9afcfe68388).

Well @Samsung, this is no date:

 3:   offset=     252 generation=0 types.Dict 
<<
	<CreationDate, (D:)>
	<Creator, (Samsung Electronics)>
	<ModDate, (D:20230511171649+04'00')>
	<Producer, (Samsung Electronics)>
>>

Will be fixed in the upcoming commit.

Hey @hhrutter , I know this issue is already closed, but we've faced the same issue but with this format:
pdfcpu: validateDateObject: <D:20230912144809Z'0> invalid date

Thanks, and very appreciate the great work on this tool that saved me tones of time.

Hi @hhrutter,

we have a lot of PDF-1.2 with no CreationDate and no ModDate, failing relaxed mode validations.
Under relaxed mode with no PieceInfo should validation pass ? commit 2d8a5b6

[hhrutter]

If there is a PieceInfo then ModDate is required.
Other than that I would have to see a stack trace or even better a sample file in order to provide a fix.
