Not really, you can push data as often as you like, the only input 
data kept is that required to produce the consolidated data.

IF and ONLY if you had a consolidation that kept 5 minute 
consolidated values, then yes, you can read that data out of an old 
RRD. AFAIK, you do not have to change the system time, but you must 
NOT perform any updates - that would instantly 'age out' the older 

On the other hand, if your highest resolution consolidation was (say) 
30 minutes, then there would NOT be any 5 minute samples stored, non 
at all.
