I wrote a basic quartz adapter for calling clojure functions by submitting a job to call a clojure function by namespace/name or submitting a closure. My write-up is here:
http://asymmetrical-view.com/2009/05/19/quartz-and-clojure.html The example quartz code is in my github sandbox: http://github.com/kyleburton/sandbox/tree/master For me the advantage of using quartz and clojure is that it's in the same JVM as other parts of the application - I don't need to create a separate command line runner which can be invoked by cron. I'm also exploring creating a scheduling service using Quartz listening on an AMQP message queue - where you can send it a message with the scheduling details (one off or recurring) a return queue and an embedded message body. At the triggering time it sends the embedded message back. This is also more flexible than Cron - it's all handled within the application and I can register and unregister the triggers. Cron would be more difficult to use for cases where I want to defer some activity by sending it to the scheduler to be returned in say 10 minutes. The scheduler service isn't in my sandbox yet, but I do plan on publishing it when its complete and I have the time.
