Hi Reinout. zc.async can be used to do cron-like activities by starting a job, to be performed after a certain time, that has a callback that reschedules another job when desired. This has the advantage over cron-like behavior because it does not reschedule until the first job is done. Other zc.async competitors have cron implemented more directly, but I found it to be very easy and flexible to do what I wanted using the zc.async approach.
