How can I set a cron and how can I execute it in Unix, Linux, and windows?

Question

I'm interested in a replacement for cron which would allow me to run various cron jobs on demand, and mark them as having been run, so they won't be run again from the schedule.

I noticed whenjobs, which looks like it may do the job. The documentation for whenjobs says that it is obsolete and has been replaced by goaljobs.

Has anyone tried out whenjobs or goaljobs.
