Yes, the revisions can be reconstructed in merely the same time, for instance it doesn't matter if you open the most recent revision or any past revision regarding system/transaction time. We also do not have to store the transaction time more than once (in the revision - root page). And if you do a fine granular modification, we usually do not copy and rewrite the whole page with currently 512 records (it depends on the versioning algorithm you use).
