It's going to an FNB account, so my experience is it should reflect in the account of the recipient by the next business day at the latest, but dated as the day of the transaction per your Standard Bank account. But bear this in mind - you must process the payment before 7.00 p.m - transactions after 7.00p.m. will be dated for the following business day.
Personally I'm setting the day before the last day as the deadline once the debit pull option is over, just to play safe. Risking a 10% penalty for the sake of one day just isn't worth it. (Same goes for fighting for the penalty to be waivered too).
