You can get one value if you use 'rrdtool xport' with the same start and 
endtime.
Using 'rrdtool last' will give you the latest update time. You can use this 
time for the 'rrdtool xport' but you have to substract the step in second of 
your database. I'm sorry but I don't know why you have to do this. ;-)
This disatvantage of this procedure is to parse the xport output with an XML 
tool.
