Applying HTML tags to parts of PHP file

[sparklywater]

Here is the full query from that section:

// ################################################## ############
// ###################### Start WTdatelineTOusertime ############
// gets dateline in unix format and converts it to visitor's time.
function WTdatelineTOusertime($dateline)
{
global $vbulletin, $vbphrase;

if ($dateline == 'Never' OR $dateline == '0')
{
return $vbphrase[never];
}

$readbable = vbdate($vbulletin->options['dateformat'], $dateline, true).' - '.vbdate($vbulletin->options['timeformat'], $dateline);

return $readbable;
}



The part in red is the part I want to apply the css class to.
