Hi! While working on the "reproducible builds" effort [1], we have noticed that pxz could not be built reproducibly. There is a small bug in the existing reproducibility patch. The output of dpkg-parsechangelog is piped to date, but date is not told to read from stdin and still uses the system time. The attached patch fixes this. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
