This feature is most commonly used in a Preference
auction. All of the bidders place their bids simultaneously. To
activate all of the bidders in the Bidders pane for bidding:
Go to the target Auction and access the Manage
area for the applicable auction.
In the Bidders List pane, select all of the bidders.
Alternatively, use <Shift + A> to select all, or to select a
set of bidders.
Click the icon that looks like a profile and select Bidders
Properties.
In Bid Time, click the button that looks like
a calendar and select the date to activate all of the bidders. Wait
for the field to draw the date and time. The time defaults to Now.
Change the time if desired using the same format provided.
