$(document).ready(function() {
alert(today());document.getElementById("serviceTime").value = today();
});

function today(){
var today=new Date();
var h=today.getFullYear();
var m=today.getMonth()+1;
var d=today.getDate();
var hh=today.getHours();
var mm=today.getMinutes();
var ss=today.getSeconds();
m= m<10?"0"+m:m;
d= d<10?"0"+d:d;
hh = hh < 10 ? "0" + hh:hh;
mm = mm < 10 ? "0" + mm:mm;
ss = ss < 10 ? "0" + ss:ss;
return h+"-"+m+"-"+d+" "+hh+":"+mm+":"+ss;
