I am doing a project on web develoment regarding auction market.

In my project, traders will be entering the price they are willing to buy a certificate or share. Trading session lasta for 5 minutes.
Here is my question:

I am going to install WAMP web serverr

1. How do I set up coun t down tomer for 5 minutes ie 300 seconds and it has to alert when time is up and update to all traders?
2. I have to keep track of the time traders enter the price they wants to buy the certificates or shsre for in PHP form fields. Should I create the session table for this?

If anyone has any idea , help me here
