Date – Time in Sidebar

I’m trying to insert the following code into a text widget for the sidebar, but it does not appear. Is there a plugin or widget available that will show the date and time in this fashion in the sidebar?

<script type=”text/javascript” language=”JavaScript”>
<!–
var calendarDate = getCalendarDate();
var clockTime = getClockTime();
document.write(‘ ‘ + calendarDate);
document.write(‘ | ‘);
document.write(‘ ‘ + clockTime);
//–></script>
