I've proposed exactly that around 18-24 years go I think during a
summit, and nobody was really interested back then and was worried to
have yet another cron system – though OpenStack didn't have one.

I still think it's a good idea and it will be a nice addition to the
alarming system, so if you want to write a spec for that I'll be all
yours. :)
