      This example uses a cron source and a log sink.

      ## Cron

      You can format dates using a "layout":

      https://golang.org/pkg/time/#Time.Format

      By default, the layout is RFC3339.

      * Cron sources are **unreliable**. Messages will not be sent when a pod is not running, which can happen at any time in Kubernetes.
      * Cron sources must not be scaled to zero. They will stop working.

      ## Log

      This logs the message.

      * Log sinks are totally reliable.
