Hi there,

I'm using the URL API in Graphite 0.9.10 and noticing something odd with the way Graphite is displaying RRD graphs.

If I display graph for the last 30 mins I can see one more data point than the last 1 hour.
I double checked the data in the RRD file by running "rrdtool fetch" and I can see the last data point.
I can duplicate this across all of my RRDs.
I also checked this with 2 and 3 hours and I can see the last data point is omitted.

Here's an example:
Time when testing is 11:15AM PST.
We have disk_free RRD from ganglia and if I show the last 30 mins graph I can see line go up to 11AM.  
However if I show the last 1 HR then graphite is showing me up to before 10:40AM. 
I checked the RRD file and I can see the last data points are at 10:36AM and 11:00AM.  
So it seems like Graphite is missing the last data point in the RRD when we do "&from=-1hour&until=-".

TimeZone is already set in localsettings.py and the apache httpd server has been rebooted multiple times since install.

Any help is much appreciated.
