As required for the upgrade I exported all my rrd's and they appear correct,
but when I performed a 'restore' on the upgraded 5.5 system the dates appeared
to become advanced by 136 years.
These are for Cacti and interestingly, cacti shows graphs for the old data, but
not for data collected after the upgrade. The rrd's are being updated, but
with a recent date.
