Hi Mehtab,

I am sorry for the delay.

I guess you want to specify a maximum period of time over which  
participants will send asks and bids. After that time, the auctioneer  
will clear the auction. To do that, you don't set this time at the  
auctioneer, but at the auction.

You set this time in the constructor. For example:

/**
  * Default constructor
  * @param auctionName A name for the auction
  * @param auctionProtocol the auction protocol
  * @param durationOfAuction duration of the auction in simulation time
  * @throws Exception
  */
public DoubleAuction(String auctionName,
	int auctionProtocol, double durationOfAuction)throws Exception {
	super(auctionName, auctionProtocol);
	this.durationOfAuction = durationOfAuction;
}

One event will be scheduled to be received by the Auction entity  
after the duration provided. When that event is received, the  
DoubleAuction, for example, calls the closeAuction() method.

You can extend DoubleAuction and implement the closeAuction() method  
that suits you. I am attaching an example of double auction that only  
receives asks and bids, puts them in lists and implements the  
closeAuction() method. It does nothing at the moment, but you can see  
where your code should be inserted.

Please let me know if you face any other problem.

Regards,

Marcos
