33:55 I think what he/she wants to know from the question is that why the addition is the proof that our DB stayed consistent across t1 and t2. I think the answer is that we are moving & manipulating money, and the way we can make sure that money was not lost somewhere in the DB is to make sure the total amount of money in the ledger (DB) at the start of the transactions is the same at the end of the transactions. In fact it should be the same all the time after every transaction. It's more finance related than DB IMHO
