Bank fee has wrong date on import in civicrm_financial_item.transaction_date incorrected uses import date rather than payment date on
On import of a transaction with a bank fee, the revenue record gets the contribution receive date correctly put into civicrm_financial_item.transaction_date but the bank fee record incorrected uses import date rather than the imported payment date.
Bug 2 in https://gist.github.com/JoeMurray/6db6a82ff6c9e593ca5301b5f8708f52
Joe to confirm the exact API calls used on import to ensure that it was not a missed or incorrect parameter, but an interpretation of this date in processing a high level call to insert a contribution including a bank fee.
