[Zope-CMF] Re: database modification time vs. content modification time

[John Waycott]

Stefan, Thanks for your response.

I think I understand this. I see now that there is a separate modified 
date in the dublin core. This will work when exporting data from one CMF 
site to another, but in my case, the files were uploaded from a plain 
filesystem via DAV; we didn't have them in a website before. I then 
manually added the titles and descriptions.

I assume I'll have to just write a form or script that lets me enter a 
new date for each document and call setModificationDate(). I still have 
the old files and can get the dates from them. It will be tedious, but I 
can't think of an automated way to do this. I'm thinking I could modify 
the properties edit form and add a field to set the modified date?
