Javascript定时循环与PHP

Question

I'm trying to display the current timestamp and refresh every second, doing this with php is too slow and has to reload the page and I know javascript doesn't, I just don't know how to, any help?

<?php
    $time = time() + 3600 * 15;
    echo $time;
?>
<meta http-equiv="refresh" content="0.5;time.php" />

Thanks in advance.

JavaScript can call up a timestamp based on your local time. Use setInterval to loop and update the timestamp given by Date.now() .

setInterval(function() {
    document.getElementById("timestamp").innerHTML = Date.now();
}, 16);

See jsFiddle .
