This is just the front end script.  Whatever you use, you have to use
*some* way to generate the "rrdtool graph" command.  Even if you do so
by hand, you could do the math and feed the proper start and end times.

The only reason I used a script is because it shows what the logic
behind the values is.

This will probably work, however where do you get 'seconds' from?
And how do you make sure it is correct?
