[Zope] cron job in zope

Hi, is there a standard hook, to say to the zope server "execute the method Myproduct.mymethod" each day/hour/min ... (like a unix cron) (okay, I could use "brute force" sending an http://...request directly from a cron shell script with telnet host 8080 ...) thanks, Michel -- _/ _/ _/_/_/ _/_/ Michel.Vayssade@UTC.fr Service Informatique _/ _/ _/ _/ T:33/0-3.44.23.49.24 Universite de Technologie _/ _/ _/ _/ F:33/0-3.44.23.46.77 BP 20.529 60205 Compiegne _/_/ _/ _/_/ _ mv@utc.fr __/www.utc.fr/~vayssade____ France
