I thought about rewriting the history so I would be something with 'git 
filter-branch' if this can also split one commit with N files into N 
commits with one commit for each file.

I found the --date parameter and read more about it. I think I need a 
kind of "git-import-files" script that imports files just like you can 
import other repositories (SVN, CVS...).

Thanks, this will be helpful for special repositories that need to 
preserve file permissions. But as long as I use git for replication I 
prefer to have the timestamp metadata directly in the commit as if I 
would commit everytime I changed a file. It's a pitty that there is no 
good versioning file system for Linux yet.
