I'm afraid the necessary support to do it properly has not yet been 
written as code. It may happen soon, I'm planning a journalling feature 
for backups onto S3 and for greater disk efficiency, and one side effect 
would be a snapshot of all files that existed at a particular point in 
time.

I don't think it even needs to be so complex. The "start date" for a file 
is the oldest revision of it that we have. All we'd need to implement this 
feature is the deletion date.

Cheers, Chris.
