There's been some discussion about this in Debian and in reproducible
builds:

  https://bugs.debian.org/783938

  https://wiki.debian.org/ReproducibleBuilds/TimestampsInDocumentationGeneratedByJavadoc

  https://tests.reproducible-builds.org/debian/issues/unstable/timestamps_in_documentation_generated_by_javadoc_issue.html
