The rather unhelpful answer is "don't start from here" ! Your system
time should not change backwards, and the simple answer is to keep
the time accurate (NTP is good for this).
By far the easiest way to deal with it is just wait the 2.2 hours you
set the clock back by and it will recover on it's own - BUT you will
effectively lose 2.2 hours of data. If you REALLY need the data then
you'll have to export the entire RRD database, modify the data in it,
then import it into a new database.
