I've cracked it but I had to cheat. This solution assumes you have an ascii
file consisting with your values to enter in the format unixdate:value on each
line e.g.
1004009400:15
1004009700:14
1004010000:13
This MUST be in data order with the oldest date first.
1. Create your rrd file
2. run rrdtool dump on the above file and save the output to a file
rrdtool dump test.rrd > test.xml
3. Edit the test.xml file and between the <lastupdate> tags enter the earliest
datetime value of your input data.
<lastupdate> 996019000 </lastupdate>
4. Restore this xml file thus
rrdtool retore test.xml test.rrd
5. Enter the data in the input file. You could do this in a loop thus;
for i in `cat input.txt`
do
rrdtool update $i
done
It's dirty but it has worked for me.
All the best.

I had the same problem last night, and my theory was shot, as I had the same
error message.
What you can do is 'rrdtool dump file.rrd > file.dump' then edit the
resulting xml file, and then use rrdtool to import the data back
into the rrd file. Works great.
You could easily make a program to insert the values for you since it
is in xml.
