[rt-users] matching null against date/datetime CustomFields

In RT4, we can create Custom Fields that have date or datetime types.

If a date/datetime Custom Field has not been set, it displays as :
CFNAME: (no value)

How do I search for tickets that have not had a value set into that
Custom Field?

Here's what I have tried:

CF.{myfieldname} = ''
CF.{myfieldname} = 'NULL'
CF.{myfieldname} = 'undef'
CF.{myfieldname} = 0
CF.{myfieldname} = '1970-01-01 00:00:00'

If it is _not_ possible to search for null, doesn't that break the
semantics of a date/datetime comparison?
