RRDtool knows about timestamps that are a whole multiple of 60, and also
at the same time a whole multiple of 1440, or 1, or 120, or 30.
It does not know about whole multiples of 864, or any other random number.
Great resourses to learn about normalization and consolidation are the
tutorials, the manual pages, and http://rrdtool.vandenbogaerdt.nl/
