sysdate doesn't seem to be available. I assume this is some DB-specific 

You seem to be implying that the DateTime object's basic unit is days but I=
think it's seconds. It might even be milliseconds... This would explain 
some of the results I'm getting by trial and error.

I've read somewhere that installing mxDateTime makes life a lot easier and 
I can believe it but I haven't yet worked out how to get Zope to use 
mxDateTime instead of DateTime. Stephan Richter's modules don't work on 
Zope 2.5.1
