No, you got what you asked for.

Each PDP is 5 seconds.
One RRA is 12 CDPs of 1 PDP per CDP. Thats 12x1x5=60 seconds.
The other is 2 CPDs of 6 PDP per CDP. Thats 2x6x5=60 seconds.

Then you update at 1200915840 and at 1200915900 (and earlier).
The updated at 1200915900 will fill the entire database between
time (1200915900-60) and 1200915900. The rest of your data is
gone.

Now you ask for a graph upto and including time 1200915840...
1200915900-60 = 1200915840. The only available data is starting
from 1200915840, not earlier.
