I tried this:
rrdtool create test.rrd -b now-10d -s 86400 DS:msgs:ABSOLUTE:86400:U:U RRA:AVERAGE:0.5:1:10

and then
rrdtool update test.rrd 1128643200:100

which returned
ERROR: illegal attempt to update using time 1128643200 when last update time is 1128776944 (minimum one second step)

What am I doing wrong?
