Hi! While working on the “reproducible builds” effort [1], we have noticed that camitk could not be built reproducibly since it uses timestamps in its manpage output. The attached patch makes camitk use the environment variable $SOURCE_DATE_EPOCH [2], which was proposed by the Debian reproducible builds team as a way to still have timestamps in documentation but make them be reproducible. The value of the timestamp will be set to the latest entry in debian/changelog. Kind Regards, akira [1] https://wiki.debian.org/ReproducibleBuilds/About [2] https://wiki.debian.org/ReproducibleBuilds/TimestampsProposal
