Anacron does not have a certain time when it's being run. That's why it's
called `anacron' (anac(h)ronistic cron ;-). Anacron can be run every 5
minutes if you want. It checks when a specific job was executed for the
last time and how often it should run. If the job has to be run again,
it'll start it (with a certain delay, that can be specified for each job).
Thanks,
