3.7 CRON for desktop PC

The Vixie cron is installed as the default for the scheduled execution of programs. It does not function well unless your system is up 24/7. For the desktop use PC, you need to install anacron over cron to address this problem. fcron package may be used as alternative.

See Schedule activity (cron, at), Section 8.6.27 for the configuration of CRON jobs.
