[Zope] How to fix a ZODB with a timestamp in the future?

Folks - In trying to pack a ZODB (Data.fs), I get the following message: FileStorageError: The database has already been packed to a later time or no changes have been made since the last pack Given this, I try to repair the Data.fs by using the fsrecover.py script in lib/python/ZODB/. In doing this, it fixes the ZODB, but resets the timestamps of objects to a date in the year 2010. Obviously this is not a good thing, so I've returned to using the backed-up version of the ZODB. Is there a way to fix this ZODB so that the mis-timed transaction is removed or changed? Thanks! -Charles
