This depends greatly on under circumstances you want reproducibility. Just timestamp of the build, or also username, hostname, SRCDIR/DESTDIR, SVN revision and FreeBSD major/minor version? Some of this can be done by placing dummy time, whoami and hostname binaries in /usr/src/tools/build/ and using those during the build but should be configurable, as some of that information could be usable for debugging.

Have a look at sendmail config files. They are about as non-reproducible as they come :-)
