Sure. For your own creations it's somewhat easier, just create your 
own timestamps. But what about existing content. Say: what if you 
have a Yihawdirectory which has grown for a while, plus a 
collection of Zwikis scattered over various Zopes, which I want to 
move into a a single new, but already existing on a bigger, greater 
and better server?

Well, for a moment I considered hacking ExportImport.py, but it's 
not obvious. That's why I'm asking whether somebody perhaps 
already has solved the problem.

There is the option of stripping all the various data.fs and combining 
them via mounting, but this is far from elegant, if it works at all.
