A well known problem with a known solution.

Please search the mailing list archives to find it.

You cannot. Use your own attribute for modification time in the future.
Forget about "bobobase_modification_time".

However, it is not necessary to export your data from Zope 2.5
and import it into Zope 2.6.1.
You can directly use your "Data.fs" in Zope 2.6.1 (provided you
have all necessary external products installed in the new installation).
