   * config/debian/cron.dinstall: Complicate the i18n export a little
       by using date/hour based directories which we then link into the
       web view. They contain a signed timestamp file now, which means
       the i18n people can take a long time to generate files, yet we
       still know exactly on which dataset their data is based on, and
       can then verify it with that. Ensures we only get descriptions for
       packages we know off (or knew of in the past 2 days).
