+/// `Last-Modified` header, defined in
+/// [RFC7232](http://tools.ietf.org/html/rfc7232#section-2.2)
+///
+/// The `Last-Modified` header field in a response provides a timestamp
+/// indicating the date and time at which the origin server believes the
+/// selected representation was last modified, as determined at the
+/// conclusion of handling the request.
+///
+/// # ABNF
+///
+/// ```text
+/// Expires = HTTP-date
+/// ```
+///
+/// # Example values
+///
+/// * `Sat, 29 Oct 1994 19:43:31 GMT`
+///
+/// # Example
+///
+/// ```
+/// # extern crate headers;
+/// use headers::LastModified;
+/// use std::time::{Duration, SystemTime};
+///
+/// let modified = LastModified::from(
+///     SystemTime::now() - Duration::from_secs(60 * 60 * 24)
+/// );
