[Zope] dtml date comparsion help

[Kelley, Sean]

Hi,
Trying to get more familiar with dtml...

How do I do a date comparison with dtml-in?

I have:
<dtml-in "portal_catalog.searchResults( meta_type='CMF Event'
                                        , sort_on='Date'
                                        , sort_order='reverse'
                                        , Subject='All Utilities'
                                        , review_state='published'
                                        )" size="10">
Some stuff  
</dtml-in>

I want to insert a dtml statement so that only the CMF events that are on or
after today show up.  Do I do my date comparison in the first line somehow
or with a dtml-if a little later?  I am trying to say if Date (date
mm/dd/yy)  >= ZopeTime (date mm/dd/yy) do something.  Problem is that I it
seems I need to use the fmt attribute on the date comparison so I am a
little comfused about syntax.

tried something like:
<dtml-if expr="Date fmt='%m/%d/%Y' >= ZopeTime fmt='%m/%d/%Y'">  but I do
not have the syntax right.
