To change your auction open and close times, go to Event > Online Bidding Dates. These dates determine when online bidding will be turned "on" and "off".
While you can change these dates at any point before or during your auction, it is not recommended that you make any changes once the auction is open for bidding. If you have to change the dates for any reason, we recommend that you contact your bidders immediately to let them know.
