You could please check if we can fix this bug for 2.7.1 beta?

fspack is trying to raise an exception, because timestamps in the database don't make sense.  So there are (at least) two problems here:

1. The database assumes time doesn't go backwards, and uses current time to build transaction ids.  Your clock going back 4 years for a while has created problems for you this way.  Probably easiest if you can revert to a backup of the database from before the system time glitch.

2. It looks like oid_repr is indeed not imported by 2.7's fspack, and that's a bug in Zope 2.7's ZODB.  You didn't see the problem before because oid_repr is only used by fspack when fspack wants to raise an exception.

When I attempt to pack the database, it raises an error:

It worked well for months, but we upgraded the bios and after restarting zope I noticed that the date was 2000, and I set it forth to 2004. Maybe this can cause the problem?
