    I propose the attached patch which does not change the default behaviour
    of pdftex but if the environment variable SOURCE_DATE_EPOCH is set it

I'm not sure.

Meanwhile, Thanh has already made changes in the pdftex source
repository, revision 724 at
(project page: https://foundry.supelec.fr/projects/pdftex/)

I append his message about it (sent privately).  Will it suffice for
you?  --karl

From: The Thanh Han
2 new commands were added. Usage examples:

% tell pdftex not to write the default CreationDate and ModDate;
% however custom values specified via \pdfinfo{} will always be outputted

\pdftrailerid{} % tell pdftex to omit trailer id, or
\pdftrailerid{abc} % provide custom value for trailer id

A minimal test file was included in the commit:
