As far as I remember, with WebIFS installed on a german Windows2000 server
machine, it will generate something like "Montag, 12. Jan 1998 08:25:56 GMT"
rather than "Monday, 12-Jan-98 09:25:56 GMT". This means, you can't use the
standard locale date formatting routines for WebDAV (or HTTP) RFC dates
(unless you force it to use the english language).

Well. The way it's done now, MS web folders won't even *mount* the directory
because of the broken date format.

I think I remember that an old version of MS web folders only accepted
ISO8691 dates if they came with a data type attribute a la

<creationdate xmlns:dt="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/"

This isn't nice, but at least it doesn't break any client. Newer versions of
web folders don't seem to have this problem.

Due to the bugs mentioned, I currently can't use WebIFS with anything beside
some special test scripts. Microsoft Webfolders (and Office) will reject
them, so it's hard to do any serious testing.

Thanks for the feedback!
