Start/Stop Timer based on Rules actions or via Workflow Module compatibility

Using this module and the Workflow module, would be the ultimate pair for ticket tracking.

With workflow, you can specify states of nodes (e.g. New, In Progress, Pending, Standby, Solved), and only allow certain states to be selected depending on the current state.

Since this module has rules support, I assumed that there was an action "Start Timer" and "Stop Timer", but sadly that isn't the case (or I missed them).

Use Case:

Basically if state is set to "In progress", start timer. If state is set to any other state, stop timer.

This would also allow the functionality where timers could be automatically stopped. Let's say at 5:00 pm no one is working with the system, you can create a rule to automatically change the Workflow states to "Standby" which would automatically trigger the rule, or event that would also stop the timer.

I really see huge potential in just either having those two rules actions, or direct compatibility. If there is a way to do this via a workaround, I'd be extremely grateful. Thanks.
