Question from the peanut gallery: are timestamp information really verboten in reproducible builds? I was led to believe that the SOURCE_DATE_EPOCH mechanism was introduced to allow programs to keep embedding this information, while giving packagers the means to assert reproducibility. https://reproducible-builds.org/docs/source-date-epoch/ I am not well-versed on the subject of reproducible builds, so I apologize if I am misunderstanding the state of things; also, since I don't think the Emacs build system uses the SOURCE_DATE_EPOCH mechanism, I realize that this idea might be out of scope for this bug report=E2=80=A6
