[Zope] Maintain Last Modified during Copy

I'm looking for a way to copy content from one database to another without updating modification times. I believe the modification times are tied to transaction IDs which may mean this isn't possible. Moving objects does not update their modification times, but, it doesn't seem to be possible to move objects from one storage to another. One option that works is to copy the entire database, remove everything I don't want, and then pack it. But this isn't ideal. Any suggestions? -- Brian Brinegar Web Services Coordinator Engineering Computer Network Purdue University
