I mean a timestamp in a larger sense-- the next word slot only tells the
timestamp for the word relative to the other words in the same sentence,
but the sentence-id tells the timestamp of the sentence relative to other
sentences heard in the past. Else you need some other way to
distinguish the later words of a sentence heard in the past from one you
are hearing right now. 

I want this so that if I want to I can use what I know of sentences heard
before to help understand the one I'm hearing now.
