title: How to set timezone for Postgres 9.4 permanently
body: <p>I'm running Postgres 9.4. Every time I change it it's returning to default GMT after I reboot,</p>
  
  <pre><code>&gt; $ psql -c 'show timezone'   
  </code></pre>
  
  <p>TimeZone  </p>
  
  <pre><code>&gt;  US/Central
  </code></pre>
  
  <p>Is there a parameter option to be added in postgres.conf?</p>
