For example, if the auction is to end at 12:00 pm, if a bid is placed at 11:59 am, the end time will be extended by 5 mins to 12:05 pm, and if another bid is then placed at 12:03 pm, the end time will be extended by 5 mins to 12:10 pm. This process will continue until no bids are received within the last five minutes of the auction end time.
