[excerpt from CHANGES.txt]

  - Added a "clock server" servertype which allows users to
         configure methods that should be called periodically as if
         they were being called by a remote user agent on one of Zope's
         HTTP ports.  This is meant to replace wget+cron for some class
         of periodic callables.

         To use, create a "clock-server" directive section anywhere
         in your zope.conf file, like so:

             method /do_stuff
             period 60
             user admin
             password 123
             host localhost
