前一段时间好象看到有人要，发出来看看。

<script>
<?php
echo "h = ".date("G",time()).";";
echo "m = ".date("i",time()).";";
echo "s = ".date("s",time()).";";
?>

function time_rota() {
s = parseInt(s,10);
m = parseInt(m,10);
h = parseInt(h,10);
s = s + 1;
if(s >= 60) {
s = 0;
m = m + 1;
if(m >= 60) {
m = 0;
h = h + 1;
if(h >= 24) {
h = 0;
}
}
}
if(s < 10){
s = "0" + s;
}
if(m < 10){
m = "0" + m;
}
if (h < 10){
h = "0" + h;
}

document.Time.CLOCK.value =" "+h+"："+m+"："+s+" "
setTimeout( 'time_rota()', 1000)
}
</script>
