[rrd-users] rrd evaluate by number

my rrd contains three rows: "octets_in", "octets_out" and "snr" captured
from a wireless router.
Is it possible by using of rrdfetch to get the difference of the last week
by octets? Or must I write me a shell script myself and make the differece
from the actual timestamp to a timestamp one week ago? Bu how can I find the
exact timestamp one week ago?

My goal is to get the traffic (octets) of the last week by number.

best regards
