This is the default text for that widget:

PHP Code:

$output = date(vB::$vbulletin->options['dateformat']) . "<br />\n"; 


The purpose of it was to show you that the widget needs your output to be assigned to the variable $output and then it will work.
WRONG:

PHP Code:

echo "hello world!"; 


CORRECT

PHP Code:

$output = "hello world!";
