Real Time Auction Script for current website

Hi, i am currently building my new website and for one part of it there is an auction house. I can code the PHP version of it, but i want it to be real time, which is a bit beyond my skill. My requirements are as follows: * Real Time "Streaming" of data so the bids and listing update automatically, sn the user doesn't have to refresh or reload the page. * One field of the auction is time left it is in the format 3H 34M which translates to 3 hours and 34 minutes left, i need this to change real time aswell so that it changes without refreshing. * Lastly i need an API so that it can be seen on external websites. There is no need to do any paypal transactions or credit card stuff i can sort that i just need you to take my current php script of my auction house and apply the above to it, so no graphics or anything that has already been done. Thanks
