Fedora 7 is affected, too. All F7 Test Updates, for example,
don't pass this check.

The Test Update announcements print changelog dates that doesn't
match the rpm --changelog query, which is off by one into the
future compared with what the spec file contains. E.g.:

metacity announcement says:

* Tue Sep 11 2007 Ray Strode <rstrode redhat com> - 2.18.5-2
- don't dereference a NULL pointer (crash on logout, leading
  to weird problems on next login, bug 243761)

rpm says:

* Wed Sep 12 2007 Ray Strode <rstrode redhat com> - 2.18.5-2
- don't dereference a NULL pointer (crash on logout, leading
  to weird problems on next login, bug 243761)


yum announcement says:

* Mon Sep 10 2007 Seth Vidal <skvidal at fedoraproject org> - 3.2.5-1
- 3.2.5
- prune unnecessary patches

rpm says:

* Tue Sep 11 2007 Seth Vidal <skvidal at fedoraproject org> - 3.2.5-1
- 3.2.5
- prune unnecessary patches
