The above example is all to get the client if you want to get the server side we can use Ajax to instance

Name: Server clock (one read, real-time display)
Function: Displays the server-side time on the client browser.
Principle:
1. Get the date and time of the service end.
2. The time difference between the server and the client can be obtained according to the client browser.
3. Server Clock = client's clock (change value) + Time difference (fixed value)

The code is as follows Copy Code
<title></title>
<body>
Current: <div id= "Time" ></div>
<script>
var XmlHttp = new ActiveXObject ("Microsoft.XMLHTTP");//Create XmlHttp Object
Xmlhttp.open ("Head", "Http://www.111cn.net", false); from which server to get the time
Xmlhttp.send (); Connecting to a server
var offset = Date.parse (Xmlhttp.getresponseheader ("Date"));//Get Time in header
Offset-= (new Date). GetTime (); Get the interval between local time and server time
function ShowTime ()//Display Time method
{
var d = new Date; Get current time
D.settime (D.gettime () +offset); Get current server time through server and local time interval
document.getElementById (' time '). Innerhtml=d.tolocalestring ()//Display server times
}
SetInterval ("ShowTime ()", "1000");
</script>
</body>
