DS type doesn't matter - it only controls how the 
data is entered into the RRD. If you multiply 
rate by time you get total, end of story.

Calculate the average over 24 hours, multiply by 
86400, and you get the total. It won't normally 
be an integer because of all the normalisation 
that goes on - but if you are VERY careful with 
your data inserts so as to avoid normalisation 
then you will get something very close and can 
round it.
