You might be able to get something working with the expression validator. It lets you specify an OGNL expression. Combined with OGNL's ability to call static methods, you might be able to hack something together like:

myDate < @java.util.Calendar@getInstance().time

I'm not sure this would actually work though, as I've never tried it.
