TemporalData has a number of properties for extracting the parts you 
need. To get the paths with time stamps use TemporalData[...]["Paths"]. 
To get the states use TemporalData[...]["States"].

I recommend looking at the details section of the documentation for 
TemporalData to see the full list of properties and read through the 
examples on that page to see how each is used.
