+/// `Expires` header, defined in [RFC7234](http://tools.ietf.org/html/rfc7234#section-5.3)
+///
+/// The `Expires` header field gives the date/time after which the
+/// response is considered stale.
+///
+/// The presence of an Expires field does not imply that the original
+/// resource will change or cease to exist at, before, or after that
+/// time.
+///
+/// # ABNF
+///
+/// ```text
+/// Expires = HTTP-date
+/// ```
+///
+/// # Example values
+/// * `Thu, 01 Dec 1994 16:00:00 GMT`
+///
+/// # Example
+///
+/// ```
+/// # extern crate headers;
+/// use headers::Expires;
+/// use std::time::{SystemTime, Duration};
+///
+/// let time = SystemTime::now() + Duration::from_secs(60 * 60 * 24);
+/// let expires = Expires::from(time);
+/// ```
