RRDtool works with intervals of a fixed duration, and also on specific start and end times. Calender months aren't of a fixed duration, and midnight local time usually is not on a suitable boundary. And then there's daylight saving in most places. This means you will have to use hourly stats. If your local time zone happens to be something else than a whole number of hours away from UTC, then even hourly stats won't do and you need to resort to e.g. 30-minute stats. Clear enough?
