There will be shortcuts. For instance, if your shell uses integer calculations (probably it does), try: rrdtool ... --end $((`date +%s` / 21600 * 21600)) ... Or, if you want to have some logging available not just for yourself but also for others, so that the problem can be reproduced, export now as you do, combined with the shortcut I proposed, and echo the entire rrdtool command line to a logfile ( echo rrdtool ... --end $now ... >> /tmp/rrd.txt ) If this actually makes a difference, it could be that all your graphs are in the undesired way. If so, subtract an hour or so from the date.
