Are you aware that RRDtool works in UTC? You should have something like --end 1422662400 --start end-2419200
Thanks for the answers. The data is indeed there, with an "rrdtool dump" I was able to see all the values (also shown by rrdgraph). In addition, fetching as Alex suggested, i.e. using exact multiples of 86400, actually gave me the output I was expecting. Thanks!
