The presentation time for each incoming frame is *already* delivered 
to each reader (in the data sink's 'after getting' function).  You do 
not need to modify any underlying code to give you this - you already 
have it!

In particular, note the function "FileSink::addData()" (in 
"liveMedia/FileSink.cpp").  It includes a "presentationTime" 
parameter.  You could modify this code (or, alternatively, write your 
own "MediaSink" subclass) to use this parameter.
