[rt-users] Change ticket status after elapsed time period

[kjcsb]

I would like to configure RT to automatically change the status of a ticket
in certain cases. An example of this would be when a ticket is set to
"waiting on customer" response. After a certain period without a response
(ideally working days rather than calendar days) we would like to resolve
the ticket. I've been unable to find the right term to search on to find the
answer to this. Any help appreciated.
