I hadn&#x27;t seen this spec before: <a href="https:&#x2F;&#x2F;reproducible-builds.org&#x2F;specs&#x2F;source-date-epoch&#x2F;" rel="nofollow">https:&#x2F;&#x2F;reproducible-builds.org&#x2F;specs&#x2F;source-date-epoch&#x2F;</a><p>Parabola&#x27;s efforts toward reproducibility have been essentially discarding timestamps by forcing them all to Jan 1, 1990 (a simple date, with a wide gap between it and the Unix epoch) <a href="https:&#x2F;&#x2F;projects.parabola.nu&#x2F;packages&#x2F;libretools.git&#x2F;tree&#x2F;src&#x2F;librefetch&#x2F;librefetch#n325" rel="nofollow">https:&#x2F;&#x2F;projects.parabola.nu&#x2F;packages&#x2F;libretools.git&#x2F;tree&#x2F;sr...</a><p>Perhaps I should add support for this to Parabola&#x27;s toolchain.
