Hi Dave:
There is no simple building block like a "run-at" record. I had a similar question some time ago, and when you search tech-talk, you might still find the answers. Things one can do:
1) run a 'cron' job on the host that basically performs a 'caput' to some PV which then triggers stuff. Trivial to set up, but then you depend on the host to trigger the IOC.
you can also run a cron job (spawn a process) on the IOC (we do that on some of ours).
Aloha, Maren
