can workflow trigger after a specified duration?

I realize the question I have above is covered by the scheduler module (http://drupal.org/project/scheduler), but I'm actually interested in having other workflow_ng 'actions' triggered at certain times than just publish/unpublishing.

If this feature is not currently available, then custom php conditions would be ok for my use... I realize those don't come easily! But maybe someone has already worked on something like this?

The reason I'm asking is that I already use workflow_ng extensively on this site, and would be great to integrate duration with the configurations I already have.

Thanks a lot!

Can you give a simple example of how this would work?

When I tried the CClinks module, it seems to only allow you to associate links with a specific content-type, and those show in the node's page $links display. This isn't ideal for what I mentioned, because publishing a node for a specific length would not be able to happen automatically, and also, if clicking a link were required, it should happen by the admin and not show on the page display with the other links.

But maybe I just don't know how to use this module properly... an example would be really helpful :)
