i have tried my best. Here my Script
<script type="text/javascript">
var now = new Date();
var calMillisecs = new Date(now.getFullYear(), now.getMonth(), now.getDate(), 17, 57, 0, 0) - now;
if (calMillisecs < 0) {
calMillisecs += 86400000;
}
setTimeout(function(){alert("Uhrzeit Erreicht !")}, calMillisecs);
</script>
Works great.
But any Ideas how i can use an official NTP Server and not the client time ?
I tried it with this
