When doing package builds, centpkg builds the man page using
pyrpkg.man_gen.generate(), and since the man page embeds the build timestamp in
the footer, the result is irreproducible. Use $SOURCE_DATE_EPOCH [1], if set, to
clamp the timestamp.
If SOURCE_DATE_EPOCH is set, but not a valid integer, this will raise an error.
I think this is appropriate, since this would most likely be a result of some
strange operator error.
Checked with:
$ PYTHONPATH=.:centpkg-0.8.2/src python centpkg-0.8.2/doc/centpkg_man_page.py
$ SOURCE_DATE_EPOCH=3001111 PYTHONPATH=.:centpkg-0.8.2/src python centpkg-0.8.2/doc/centpkg_man_page.py
The only difference is the date in the footer.
