It will do, by design, if you feed in updates out of order.
If feeding data like that is a fundamental part of your system 
design, then RRD is not the right tool for your task.

If you need to insert a screw, then a hammer isn't the right tool. 
The fact that the hammer doesn't turn the screw isn't a fault of the 
design of the hammer - it's simply a symptom of the tool not being 
matched to the job.


It may be that a combination of tools is what you need. Perhaps some 
short-term random access database that allows you to do inserts 
out-of-order, and then take the data from that (after some suitable 
period to allow everything to be sorted out) and stuff it into RRD 
for long term storage.
