AppleShare IP 6.2: File Modification Dates Changed

I have an AppleShare IP 6.2 server. I notice that sometimes when my users copy files to the server that the modification date of the files is changed to the time at which they were copied to the server. How can I resolve this?
This was an issue in AppleShare IP 6.2 when copying files to the server via AppleShare (AFP). Files copied via FTP and SMB were not affected.

This issue is addressed in AppleShare IP 6.3. The update to AppleShare IP 6.3 is available from the Apple Software Updates Web site at http://www.apple.com/swupdates.
