It's very promising. I just tried to update my past-due tasks to the current date. It pulled most, but not all of my tasks. The only thing that I can think of that might be different about those tasks that weren't pulled could be that those tasks were ones where I have changed the status (pending to complete back to pending) several times.

Once I combine this with an alarmed command to run this automatically, this should improve the usefulness of the task list considerably for me.
