From https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1093201: Whilst working on the Reproducible Builds effort [0], we noticed that rsync could not be built reproducibly.
This is because the date in the manual page can vary depending on whether there is a .git directory and the modification time of version.h and Mafile, which might get modified when patching via quilt.
A patch is attached that makes this use SOURCE_DATE_EPOCH, which will always be reliable.
