rrdfetch won't - it will give you the raw data from an rra. You can 
use rrdgraph to do this, ask for a "graph" from x-86400 to x (where x 
is "last midnight"), use a vdef to get a single value for the rra 
being "graphed", and then gprint to print it. Just don't use any 
graph commands and it will simply spit out the value instead of 
drawing a graph.
