Dear Maintainer,
While working on the “reproducible builds” effort [1], we have noticed
that several packages (like ruby-build) use asciidoctor in their
building process, resulting in timestamps in man files that break
reproducibility.
To solve this kind of issues, it would be nice to have asciidoctor
support the SOURCE_DATE_EPOCH environment variable [2].
See the attached patch for a proposed solution.
Regards,
Alexis Bienvenüe.
