title: How to set timezone for Postgres psql?
body: <p>How do I set timezone for psql to something other than my default (US/Central)? Here's what I've tried so far:</p>
  
  <pre><code>$ psql
  psql (9.1.4, server 9.0.4)
  ...
  
  $ psql -c 'show timezone'
    TimeZone  
  ------------
   US/Central
  
  $ psql --set=timezone=US/Eastern -c 'show timezone'
    TimeZone  
  ------------
   US/Central
  
  $ psql --variable=timezone=US/Eastern -c 'show timezone'
    TimeZone  
  ------------
   US/Central
  </code></pre>
  
  <p><em>Edit</em>: I don't want to change the server timezone, just the client.</p>
  
  <p><em>Edit #2</em>: I want it in non-interactive mode.</p>
