It pulls values from input elements, posts them via Ajax using jQuery, and places the returned HTML in a specified target (or executes some returned Javascript). It relies on jQuery for the actual Ajax calls, so if you need to do anything more sophisticated, you can just use jQuery directly. You should be able to handle whatever Ajax you need.

Otherwise, you should be able to implement your own timer. Note, anything you can do with Ajax is technically possible with web2py -- web2py is a server-side framework and is happy to receive Ajax requests and return responses. Most of the effort will be on the client side -- for that, web2py provides some convenience methods, but you are free to use other third-party libraries or build your own JS/Ajax solution.
