Not sure if this would work as I'm not yet familiar with the way RDD stores
its data...I know it didn't work on mrtg because of the way the logfile
stores info, you just get the last value sampled repeated for the times
which MRTG was not running.   

Someone suggested writing another program to parse the mrtg's logfiles,
calulate the average between 9-3, then write that agerage back to the
logfile for all other times so it would then figure the weekly,monthly,and
yearly averages correctly.  I'll be honest...I not THAT good.  

Someone said that I could do it with RDD, here is their note:

No idea what I can do at this point.  I may go ahead and try the cron
method. Thanks for your input!
