Why not just use Cronnix or cron itself in OS X?
‘cron’ is the built in scheduling program that runs in all Unix based systems, including Mac OS X, and has a similar purpose to Script Timer. Both the system and the user can use it to schedule the running of processes. Cronnix is a third party front end program for cron with a Graphical User Interface. Script Timer has several advantages over cron when it comes to scheduling the running of AppleScript scripts, largely because a) cron is a general purpose Unix utility, b) most scripts must be saved as applications to be run by cron, and c) cron lacks some of the scheduling possibilities of Script Timer. While Cronnix makes using cron much easier for the non Unix expert, it is still cron that does the scheduling, so that the same limitations apply. For a detailed comparison of Script Timer, Cronnix, and cron, see the Product Comparison Page. 2.
