Thanks Casey. In my case, I transered some ZWiki from an old server to a new one. Zwiki pages display their dates based on their bobobase_modification_time :(( I added to the Zwiki a custom view based on the most recent Zwiki pages. This view is now screwed. When CMF object keep the dates in the meta data. Of course a "retain existing object dates" would be fair in the import form (like for the ownership).

The answer is that you should not rely on bobobase_mod_time as the application modification date of your objects. You have uncovered a good reason why. Your application should instead store and update the mod date on its own, like the CMF does. [...]
