Grrr.  Why is this?  Can't there be a -force switch or something 
to tell rrdtool it's OK to update an old time point?

I did that, but it took like 20 minutes to dump, edit, and restore 
a single database(they are large).  Just doing an update would be 
much easier as well as ideal since an update could be automated. I 
guess I could automate the dump/edit/restore procedure, but that 
would be a major PITA and 'band-aid' fix in my opinion.
