title: Time RFC3339 format, to timezone.
body: <p>I need to convert this time to UTC+00 timezone time. It gives me a date with timezone depending from where user is in RFC3339 format. So it looks like this </p>
  
  <pre><code>2000-01-01T00:00:00+02:00
  </code></pre>
  
  <p>I need to use the +02 timezone and correctly calculate the date.
  So my idea is: Do I just check what is the last 00:00 and - or + days from the date? Or is there actually functions to use from php side like <code>time_convert( )</code> etc..?</p>
  
  <p>I've made this, how ever I am not sure if its correct way of doing it.</p>
  
  <pre><code>$date = '2000-01-01 00:00:00+02:00';
  $date_date = substr($date, 0, 19);
  $add_hours = substr($date, 19, 22)*3600;
  $add_mins = substr($date, 23, 25)*60;
  $add_secs = $add_hours+$add_mins;
  $date = date('Y-m-d H:m:i', strtotime($date_date)+$add_secs);
  </code></pre>
