Hi, I am little confused by --start/--end options of rrd graph. I need to plot a graph that ends at nearest 12:00. How to do that? I read about AT-TIME format, but there is a difference between at and rrdtool. When I use "12:00" with 'at', it assumes nearest 12:00 (today 12:00 or tomorrow 12:00), but 'rrdtool' uses today 12:00 always.
