The header names are case-insensitive, see:

http://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html

section 4.2.  The dates you show are valid as per

http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html

section 3.3.1.  The second date format is in common use but obsolete so
it probably should not be used in new applications, but according to the
RFC, in any case, "HTTP/1.1 clients and servers that parse the date
value MUST accept all three formats" and those three formats include the
two you show above.  So can you specifically tell us what the problem is
with the above headers, and which HTTP server doesn't accept it as
valid?

Also, please force yourself to write a proper bug report.  You don't say
what you expected to happen, what actually happened (instead you ask us
to guess which one is from Gnus), and what you did to make the bug
occur.
