php script only parse once per request, the js variable server_now is always same.

var time = <?=time()?>;

console.log(time);

function increment() {
    time += 10;
    console.log(time);
}

setInterval("increment()", 10 * 1000);

But if you would like to acquire the exact server time, there should be a server API for that purpose, and then use ajax to invoke that API.

The php echo time will only update on page reload. It won't update using setInterval.
