    scripts/mk: Export SOURCE_DATE_EPOCH
    
    The minimally guaranteed entry point to build packages is the
    debian/rules file, dpkg-buildpackage and any environment it sets up
    cannot be relied upon.
    
    Export this variable from pkg-info.mk preset from the debian/changelog
    Timestamp.
    
    Closes: #824572
