OK, I have found another solution making use of non domestic clock.
- Copy following code and save as 
blog/protected/components/Clock.php. 
[php]
<?php
class Clock extends Portlet
{
        public $title='Clock';
        protected function renderContent()
        {
                $this->render('clock');
        }
}
- Copy following code and save as 
blog/protected/components/views/clock.php. 
<center>
<embed src="http://www.clocklink.com/clocks/0001-gray.swf?TimeZone=JST&Place=&"
  width="140" height="140" wmode="transparent" type="application/x-shockwave-flash">
</center>
> Note. You may want to change the timezone from JST to whatever.
- Add following line to 
blog/protected/views/layouts/main.php. 
[php]
    <?php $this->widget('Recent Comment'); ?>
+    <?php $this->widget('Clock'); ?>
Terms & Conditions:
I am using the world clock from http://www.clocklink.com/, thus the user should obey the terms and conditions of this site, though it is free of charge.
Have fun ![]()
