	Perusing my news spool directory tree, I noticed two different
formats for Expires: headers.  All the articles in news.announce.conferences
have headers which look like the following (some header lines deleted):

+----------------
|Newsgroups: news.announce.conferences
|Subject: CFP: Optical Computing (April 8-12 '90, Japan) (In English)
|Message-ID: <1989Sep5.000014.11070@mcmi.uucp>
|Date: 5 Sep 89 00:00:14 GMT
|Expires: 11/10/89
|Sender: denny@mcmi.uucp (Denny Page)
|Approved: denny@mcmi
+----------------

while the articles in  news.newusers.questions have headers like this:

+----------------
|From: tneff@bfmny0.UU.NET (Tom Neff)
|Newsgroups: news.newusers.questions
|Subject: When to Post, When to Mail?
|Message-ID: <14644@bfmny0.UU.NET>
|Date: 10 Sep 89 01:55:26 GMT
|Expires: 10 Oct 89 00:00:00 GMT
+----------------

	It was always my understanding that the proper "Expires: " format is
as in the second example.  Is the first (mm/dd/yy) also legal?
