Yes it is interesting on the length of time it takes to transfer money from PayPal to a bank account.  Normal bank to bank transactions happen overnight (if done before 7.00pm).  

On the other side of it, if a payment is made by e-Cheque, PayPal take the funds from the account the same day, but the receiver of the funds does not see the money for roughly 5 days.  Strange really, because if the bank allows PayPal to make that withdrawal from an account, there must be clear funds there for the transaction to happen - otherwise the withdrawal would be denied.  There is no excuse for the time delay other than PayPal is making money on the short term money market.
