Excellent -- I'm glad that helped.  Note that for Zope 2.6, we have
added some new index types to deal more directly with such problems:

   - DateIndex:  a FieldIndex which knows it is for DateTimes,
     and indexes a much more efficient (both space and time!)
     representation;

   - DateRangeIndex:  indexes a pair of DateTimes, allowing the specific
     query you had trouble with to go *much* faster;

   - TopicIndex:  indexes values which pass user-defined filters, effectively
     "precomputing" a frequently-used catalog query.
