[rrd-users] Re: newbie question (creating an rrd that is updated occasionally)...

actually, that's the dilemma.
let's say that I created the rrd w/:
rrdtool create foo.rrd -b -100days -s X  DS:...etc.. RRA:LAST:...etc..
where X = # of secs in 30 days.
Now, if I update it w/ timestamp, T, where T may not lie at the
beginning of the month, I get strange results when I fetch foo.rrd.
