Your options are HTTP requests or sockets.

If your requirement is 1s on the dot, you can't do it with HTTP
requests, as there is no guarantee a web server will respond within 1
second of a request firing off.

A socket is much faster, as it's a persistent connection which can
receive events (there is still no 100% guarantee of a reply every 1
second, but you'll have more success adhering to this with sockets than
HTTP requests - less overhead and not polling or request/response
based).

You could do with fine with javascript and HTTP if, instead of a firm 1s
requirement, you just make chained requests/local updates (think -
instead of using a setInterval javascript call to poll the server on a
1000ms timeout, recursively call your javascript polling function as
part of the success condition).

Maybe that would look (to the user) like an update at the 1s mark, 3s
mark, 8s mark etc.

That's going to be the best you'll get with shared hosting imho.
