Subject: CreationDate in PDF files' metadata


I document my software using DocBook5 in a Debian GNU/Linux box. When the PDF
files are generated, the CreationDate field gets filled-up using a new value at
each run. This is a problem in our Debian effort to have "reproducible builds"
[0] with the "forensic science" idea that the same code should produce the same
binaries bit-by-bit [1].

It seems that FOP is responsible for filling-in the CreationDate field.
Are you aware of a method to direct FOP in some manner to fill-in that
CreationDate with a constant value?

Thank you for your kind attention,
