title: Yii2 save time as UTC to database but display in other timezone
body: <p>Is there an easy way to save date &amp; time in UTC, but when displaying dates and times to have them convert to specific timezones? I've added </p>
  
  <pre><code>'formatter'  =&gt; [
      'class' =&gt; 'yii\i18n\Formatter',
      'timeZone'        =&gt; 'America/New York',
  ],
  </code></pre>
  
  <p>To my config but everything now saves as in EST timezone in the database. I want the database to always be UTC and have control over what timezone to display when printing out the time &amp; date in php.</p>
  
  <p>Basically I wish <code>formatter</code> had a separate setting for controlling the format going into the database and another setting to control the format for display purposes (as users can be in different timezones).</p>
