File information

The English version of this hotfix has the file attributes (or later file attributes) that are listed in the following table. The dates and times for these files are listed in Coordinated Universal Time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time tool in Control Panel.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

When you copy a file to a WebDAV server by using the Windows XP WebClient, this process involves two internal steps:

1. WebClient copies an empty file (0 bytes) and then sets the file attributes.
2. WebClient copies the file contents and then sets the file attributes.

Notes

• If you copy an empty file to a WebDAV server, WebClient performs only step 1. Therefore, the time stamp is correct in this situation.
• The Microsoft Data Access Internet Publishing Provider DAV client does not support DAV attributes.

This problem occurs only in the following installations:

• Windows Server 2003
• Windows Server 2003 SP1
• Windows XP SP2
• Windows XP SP1 with the hotfix from the following Microsoft Knowledge Base article installed:
  820193 Last Modified time value is not updated correctly when you modify any file on a WebDAV share
