Hi Rob,

you can 'dump' and edit the xml to 'reset' the time ... but note,
that an rrdtool update is a rather complex operation, so reverting
it is equaly complex and always coupled with some loss of data ...

better is to first make sure your time is right ...

When the unit starts up the time is incorrect and I have on a number of occasions had the system log data with a time stamp that is 10hrs in front of real time.  When the clock is corrected rrd will not accept the data until the time stamp is greater than the last logged.  Anyway of somehow forcing acceptance or deletion of last value that was logged.
