Get scheduled rules in rule I need to get the date of a scheduled rule and display it to the user.

I also would like (Not necessarily required, I can also use an invisible CCK field) to use the existence of this schedule as a condition in yet another rule.

Is it possible to get this using rules alone or do I need to use the "Execute custom PHP code" condition/action to find them?
What about doing it the other way around? Use a date field and triggering the rule according to it?
