how to add link to this date script?

[pixie6]

I have a question regarding having a link on the current day. how would i display a link on the current day to a page? when i add a link to this part of the
script:

/*
        Return the URL to link to  for a given date.
        You must override this method if you want to activate the date linking
        feature of the calendar.

    Note: If you return an empty string from this function, no navigation link will
    be displayed. This is the default behaviour.
*/
function getDateLink($day, $month, $year)

{
    return "calendar/current.php";
}

it displays the link on every day of the calendar , i just want it in the current day.

thank you ...
