[Zope] Matching a date that's in a Zcatalog field index

[Chris Muldrow]

I've set a CreateDate property on a bunch of files--basically, i grab the
ZopeTime at the time of the DTML Document's creation and write it to a
CreateDate property of type date. Now I'm trying to pull individual dates
out of the Catalog--for instance, to show all of the stories written today.
What's the proper syntax for matching this stuff? This doesn't work:

<dtml-in "NewsCatalog(CreateDate.Date()=_.ZopeTime().Date())">

</dtml-in>

Thanks! - Chris
