If you want to apply daily diff to an osm file you can do it and write 
only new file in some bbox or boundary, thats how I use it:

osmosis  --read-xml-change file="daily.osc" --read-xml file="base.osm" 
--apply-change --bounding-polygon clipIncompleteEntities="true" 
file="border.poly" --write-xml file="new.osm"

I use bounding polygon but bbox should work as well

If you want only changes you use osmosis to get change.osc from base.osm 
to new.osm
