<h4 class="method" id="method_format">format($pattern_key = 'local', $timezone = null)</h4>
<p>
The <strong>format</strong> method returns a formatted date as specified by the pattern key. The
patterns are defined in the <kbd>fuel/core/config/date.php</kbd> config file - you can add your own
by creating a similar file in <kbd>app/config</kbd>.
</p>
<p class="note">This method uses patterns for the <a href="http://www.php.net/manual/en/function.strftime.php" target="_blank">strftime()</a>
function instead of <kbd>date()</kbd> to allow for i18n.</p>
<p>
If you don't pass a timezone, the timezone set on the current Date object will be used when formatting the result. By default,
this is the system timezone, unless you have altered it by calling the <kbd>set_timezone()</kbd> method. You can also pass
<kbd>true</kbd> which will cause the global display_timezone to be used.
</p>
<p class="note">You can use the display_timezone to globally set a timezone to convert to, for example from a user profile
setting when a user is logged in. This will allow all dates to be displayed in the users local timezone.</p>
