[rrd-users] delayed updates

We have a monitoring service which collects metrics.  If that service
is down, we queue up the stats to be pushed into RRD later.  Once the
service comes back online, we want to push the latest metric data
along with the older data (not all at once so as to not overwhelm the
service once it is back online) so we can fill in the gap in RRD.  My
question is with rrdupdate, it does not like updating an RRD file with
older data.  If we push current data into an RRD file, is it possible
to push older data into it since the lastupdated timestamp will be
greater?  Is it possible to fill in the gap without having to send all
the old data at once?
