[Zope] and question

[complaw]

First, thanks for the help these last several days.  I'm glad to report that I
have a useful Zope site up and running that is the envy of the law firm.

Now its time to get a little fancy.  Unfortunately, after having read the DTML
Reference, and the Zope Quick Reference, I still haven't been able to figure out
how to get today's date into a dtml-var.  Case in point:

I want to put a table of dates and hyperlinks.  If the day has already passed, I
want to shade the table cell (<td bgcolor="gray">).  In this case, the object
has a date property called event_date.

<table>
        <tr>
          <dtml-if expr="event_date < DateTime()">
                <td bgcolor="gray">
          <dtml-else>
                <td bgcolor="white">
          </dtml-if>            
        </td>
</table>

The above code gives me a NameError.

Another example would be to simply get the integer value of the year so that it
can be included in a copyright statement.  E.g.,

Copyright &copy; <dtml-var Year()>, All rights reserved.

Unfortunately, this doesn't work either.

Can someone point me in the right direction?
