       If the Time dimension had attribute hasAll="false" and a range such as
       outside dimension range
           ([Time].CurrentMember : [Time].CurrentMember.Lag(6000.0)
       within a given year
           ([Time].CurrentMember : [Time].CurrentMember.Lag(3.0)
       then one gets the same answer as hasAll="true", but if the query
       spans a year boundary
           ([Time].CurrentMember : [Time].CurrentMember.Lag(60.0)
       then hasAll="false" fails.
