What timezone are you operating in? I would guess that this is 3 hours of GMT (UTC) (3 * 60 * 60 = 10800) I have a similar problem as I am operating EST which is 4 hours away from UTC. As such all my boundary points appear at 20:00
The explanation has been posted several times as to the reasons why this happens, along with some of the possible work arounds (im not trying to be deliberately unhelpful by not explaining any further but somebody more knowledgeable then me can probably do a better job.... Try searching for timezone) However I would again like to raise the question of future versions of RRD possibly being flexible around specifying the origin for each RRD via the start parameter of rrdcreate rather then simply being based on step multiples from the unix epoch (which is measured in GMT/UTC). Having watched this archive for the last several months this is seems to be a common query especially as RRD becomes more global.... Each time the same work around are submitted about having twenty-four 1 hour consolidated data points and people re-engineering their database from there. Myself included (Thank you Alex for the initial help) although I still have not managed to take advantage of all the consolidation and round-robin functions in any other timezone apart from GMT! Anyway apologies to Giovane for not being extremely helpful but I would be interested in a wider discussion especially with some of the core architects as these guys are the genius' behind this stuff.

Man, It looks insane. I create a rrd file like this: rrdtool create dados.rrd --start 1095130800 --step 86400 DS:download:GAUGE:86400:0:U RRA:AVERAGE:0.5:1:400 RRA:AVERAGE:0.5:30:100 RRA:AVERAGE:0.5:365:2 My start is 1095130800 , midnight of 09/14/04. And my step is 86400, 1 day in seconds. So my next update data should be 09/15/04 (1095217200). But when I update my file, there is a difference of 10800 seconds from time I suppose be correct (1095217200) and the updated point (1095292800). Why I got this when I type rrdtool fetch dados.rrd AVERAGE --start 1095217200 |more ? 1095292800: nan 1095379200: nan 1095465600: nan ... and then goes. Why there is 10800 diff??? Pls help me!
