[jira] [Commented] (FOP-2854) CreationDate in PDF metadata breaks reproducible builds

JIRA jira@apache.org

    [ https://issues.apache.org/jira/browse/FOP-2854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16890198#comment-16890198 ]

Chris Bowditch commented on FOP-2854:
-------------------------------------

I don't see how fixing the create date to the Unix Epoch will help you compare linux distros either. As I mentioned above if you regenerate a PDF File, internal IDs could change as well as the date. So an alternative means of comparing PDFs within Linux distros is needed. Or perhaps a PDF should be treated as static when rebuilding the Linux distro

> Greetings,
> I would like to report that the CreationDate value that is set in the PDF file changes at each run. This is problematic because that makes it impossible to run FOP in the context of reproducible builds (see https://wiki.debian.org/ReproducibleBuilds).
> Would it be possible to create an option to set that date value manually or some equivalent solution to this problem ?
> Thank you so much for your work on FOP !
> Regards,
> Filippo
