It seems to me that the FTP server doesnt support MDTM for changing file timestamps?  Is this the case or am I doing something wrong?  If it is the case, is there any prospect that it might be supported in the future?

Well, we tested it with FileZilla and SmartFTP, etc, and it seems to work fine. Which FTP client do you use?

You can also consider using DriveHQ FileManager, which has a lot more and better features than regular FTP, e.g. group sharing and folder synchronization, etc.
