<p>Write an HTTP <strong>server</strong> that serves JSON data when it receives a GET request to the path '/api/parsetime'. Expect the request to contain a query string with a key 'iso' and an ISO-format time as the value.</p>
<p>For example:</p>
<p> /api/parsetime?iso=2013-08-10T12:10:15.474Z</p>
<p>The JSON response should contain only 'hour', 'minute' and 'second' properties. For example:</p>
<pre><code class="lang-json">{
<span class="hljs-string">"hour"</span>: <span class="hljs-number">14</span>,
<span class="hljs-string">"minute"</span>: <span class="hljs-number">23</span>,
<span class="hljs-string">"second"</span>: <span class="hljs-number">15</span>
}
</code></pre>
<p>Add second endpoint for the path '/api/unixtime' which accepts the same query string but returns UNIX epoch time in milliseconds (the number of milliseconds since 1 Jan 1970 00:00:00 UTC) under the property 'unixtime'. For example:</p>
<pre><code class="lang-json">{ <span class="hljs-string">"unixtime"</span>: <span class="hljs-number">1376136615474</span> }
</code></pre>
<p>Your server should listen on the port provided by the first argument to your program.</p>
<hr>
<h2 id="hints">HINTS</h2>
<p>The <code>request</code> object from an HTTP server has a <code>url</code> property that you will need to use to <em>"route"</em> your requests for the two endpoints.</p>
<p>You can parse the URL and query string using the Node core 'url' module. <code>url.parse(request.url, true)</code> will parse content of request.url and provide you with an object with helpful properties.</p>
<p>For example, on the command prompt, type:</p>
<pre><code class="lang-sh">$ node -pe <span class="hljs-string">"require('url').parse('/test?q=1', true)"</span>
</code></pre>
<p>Documentation on the <code>url</code> module can be found by pointing your browser here:
<a href="../node_apidoc/url.html">/node_apidoc/url.html</a></p>
<p>Your response should be in a JSON string format. Look at <code>JSON.stringify()</code> for more information.</p>
<p>You should also be a good web citizen and set the Content-Type properly:</p>
<pre><code class="lang-js">res.writeHead(<span class="hljs-number">200</span>, { <span class="hljs-string">'Content-Type'</span>: <span class="hljs-string">'application/json'</span> })
</code></pre>
<p>The JavaScript <code>Date</code> object can print dates in ISO format, e.g. <code>new Date().toISOString()</code>. It can also parse this format if you pass the string into the <code>Date</code> constructor. <code>Date#getTime()</code> will also
come in handy.</p>
