Google Maps API - Capture Traffic Augmented Travel Time as text value?

I am working on a script that generates travel distances using google maps, then writes the end result into an excel spreadsheet. I have been pretty lucky in that most of the heavy lifting has been done for me through a TuFAT script from 2006, but I need one more piece of information to make the project 100% useful.

When you use google maps proper for driving directions, you can see the travel time along with the estimated time (including traffic). I have no idea how to call/capture the traffic-augmented time by itself for insertion into my project.

Any help would be greatly, GREATLY appreciated.

the files driving the app are located at http://216.55.142.78/distance%20calc.zip if looking at the code would help any.
