if understand it correctly, lets say the page has 2000 granules of stuff on 
it, and you stamp the first page 1800, that implies you drop the first 200 
granules worth. I'm not sure how a negative end time could even make 
sense... and i'm also of the opinion that granule pos is unsigned 
with -1(2's complement) having a special value ie 2^64-1. There's certainly 
nothing in the spec that suggests this is a signed value.

Zen.
