<p>Multiple HTTP header fields store timestamps.
For example a response created on May 15, 2015 may contain the header
<code>Date: Fri, 15 May 2015 15:34:21 GMT</code>. Since the timestamp does not
contain any timezone or leap second information it is equvivalent to
writing 1431696861 Unix time. Rusts <code>SystemTime</code> is used to store
these timestamps.</p>
<p>This crate provides two public functions:</p>
<ul>
<li><code>parse_http_date</code> to parse a HTTP datetime string to a system time</li>
<li><code>fmt_http_date</code> to format a system time to a IMF-fixdate</li>
</ul>
<p>In addition it exposes the <code>HttpDate</code> type that can be used to parse
and format timestamps. Convert a sytem time to <code>HttpDate</code> and vice versa.
The <code>HttpType</code> (8 bytes) is smaller than <code>SystemTime</code> (16 bytes) and
using the display impl avoids a temporary allocation.</p>
