My first node.js socket server

socketExample.js

require('datejs');
require('sys');
var net = require('net');

var sockets = new Array();
var server = net.createServer();

server.once('connection', function () {

    setInterval(function(){
        var a = Date.today().setTimeToNow();
        for(i = sockets.length; i > -1; i--){
            try
            {
                sockets[i].write(a.toString() + ' no of clients:' + sockets.length + '\n');
            }
            catch(err)
            {
                if (typeof sockets[i] != 'undefined')
                    sockets.splice(i, 1);
            }
        }
    }, 2000);
})

server.on('connection', function(socket){
    sockets.push(socket);
})

server.listen(8123);
