Glen Mazza commented on KARAF-739:
----------------------------------

Karaf can perhaps rely on cron expressions to designate frequency:

> There are many cases that cellar requires the implementation of task that will be executed
repeaditly (something like Timer/TimerTask). Especially tasks that are related to node discovery,
ping etc.
> What I imagine is an interface that describes the delay/period of the task and a service
listener that wraps the service implementation in TimerTask.
