title: Why do I get an "invalid zone in SetDate" error when using Date::Manip?
body: <p>I have some code that I'm running with Perl 5.20 on Debian 8.1. But I'm getting a warning and an error in the following line:</p>
  
  <pre><code>Date::Manip::DM6::Date_Init("TZ=+0430");
  </code></pre>
  
  <p>Warning:</p>
  
  <pre class="lang-none prettyprint-override"><code>WARNING: the TZ Date::Manip config variable is deprecated
           and will be removed in March 2016.  Please use
           the SetDate or ForceDate config variables instead.
  </code></pre>
