well that looks like it's part of the flash object, so it's probably just a simple counter function that updates a text area on the flash stage every 1 second, and resets every time new data is retrieved. 

 

You can do something similar with javascript using settimeout() to call a function that recursively calls itself, setting settimeout over and over.  just google for a javascript clock tutorial to get the idea as far as counting in general, and as far as it resetting on last update, well you would have that reset back to 0 every time the page makes a new request or through ajax or whatever.
