Form 26QB - Date of Payment / Credit made to seller

Could someone please tell for the Form 26QB which is filled for property over 50 Lak,  there is a field "Date of Payment / Credit made to seller".

what is the difference between Date of payment  and Date of credit to seller ? 

Is it something like say for example, I place an NEFT transfer request with my bank to pay installment to builder at May 01 11 PM IST  and amount gets deducted from my account but  it  gets credited to builder account say on May 02, 01 AM IST  , then Date of Payment will be May 01 but date of credit will be May 02  and then for this field any of these May 01 or May 02 are correct to fill in or what exactly should be filled in ? please confirm.
