Looks like some problems with the timestamps here.  RRD will not add any data 
older than the youngest timestamp that currently exists in the RRD file.

Here the line with the timestamp 1086639746 occurs before the timestamp 1063900187.

And you're pulling the time from the wrong column.  The number in the last set 
of parentheses should be the timestamp, not the number less than one second.

Best,
Blair
