The answer to this is probably RTFM, but in summary;
When entering data into RRD you specify the time of the samples, with 'N'
being a convenient shorthand for "Now". This means you can put whatever you
like as the time of the sample, with the only limitation being that sample
times cannot "go backwards" in time. Times are specified using integers, so
0.3sec times are not possible unless you invent your own timescale and scale
fractions of a sec up to integer values.
Resampling is not a scary thing that needs to be worked around. All it does
is adjust input samples to fixed interval times. If you know the sample
values at the exact times, entering them at those times will avoid
resampling. If you don't know the true sample values at the exact times,
then you probably really want resampling, despite any uneasiness you feel
about it :-)
