title: Date timezone conversion socket.io
body: <p>I'm writing a chat program using node.js and socket.io. When a user sends a message, I'd like the time at which they sent it to be emitted. Instead of the Date data being in the timezone of the person who sent it, however, I'd like it to be converted to the timezones of the respective recievers. Will JavaScript take care of this automatically, or is it something I need to fix?</p>
  
  <pre><code>socket.emit('chat', {
      message: 'message',
      date: new Date()
  }
  </code></pre>
