Yep, lets make it the TS ref date. Moving this

Date effectiveStartDate =
   (startDate <= today && today <= endDate) ? today : startDate;

into:

Date effectiveStartDate =
    (startDate <= settlementDate && settlementDate <= endDate) ?
        settlementDate : startDate;

works for both cds engines.

There will still be problems if:
 probability_->referenceDate() > discountCurve_->referenceDate()

I havent tested it much though.
