[Orca-users] Re: differences in data inputfile - graph (integer / decimal)

I think it is RRD, but it could be or Orca, but somewhere the time in
seconds gets rounded to a multiple of your interval, AND the data values
are adjusted to those times.  This is useful if your data points are
sampled at approximately the interval time, 300 seconds here, but not
exactly 300 seconds.  The data values adjusted to the 300 second intervals
which almost certainly will incur fractional values.

Looking at your timestamp colums these values are not an integral multiple
of 300 there is a remainder of 32 seconds.
If the true sample values are important and not the resampled values then
ensure your timestamps are an integral multiple of the interval.

Blair,
would it be a reasonable to have an option in orca that adjusts the
timestamp to the nearest integral interval when it adds data to the RRDs ?
