It's an HTTP-date.

HTTP-date is a wierd beast in that it's an asymmetric specification,
where parsing and composing differs. The BNF specifies many formats
everyone must understand, but the notes clarify that only rfc1123-date
may be sent.

Because of this each use of HTTP-date stresses this, in a best effort to
ensure no implementer mistakenly thinks that it's valid to send any of
the HTTP-date variants that must be accepted.
