The "fPresentationTime" variable that is set by a source object must 
be aligned with 'wall clock time' - i.e. the time that you would get 
by calling "gettimeofday()".  Therefore, if your original timestamps 
come from some other time base, you must first add or subtract an 
appropriate offset before you assign it to "fPresentationTime".
