<p>This is a PNG version of the SVG image from <a href="//commons.wikimedia.org/wiki/File:2007-02-20_time_zones_white_bck.svg" class="mw-redirect" title="File:2007-02-20 time zones white bck.svg">here</a>. It is preferable to use the SVG version, but for some reason it isn't displaying properly so I have uploaded this as a temporary measure.
