Hi @hhrutter

We're facing an issue where pdf validation is unsuccessful due to the following validation error pdfcpu: validateDateObject: <D:20230912144809Z'0> invalid date

We're able to open / view files with such date format.
It fails specifically when calling api.PageCount(...) function.

Here is the full error trace:
