Synchronizes local browser time with server time using clock synchronization algorithm, similar to NTP.

##Installation

1. Ensure angular, socket.io and ng-server-time are installed correctly

   npm install socket.io
   npm install angular
   npm install ng-server-time

2. Ensure you have an angular socket.io factory such as this one, it is required by the server time factory:

   app.factory('socket', function() {
      var socket = io.connect();
      return socket;
   });

3. Include ng-server-time-factory.min.js:

    <script src="/socket.io.js"></script>
    <script src="/angular.min.js"></script>
    <script src="/ng-server-time-factory.min.js"></script>
    <script src="/my-angular-app.js"></script>

4. Initilaize the socket on the server:

   var server_time = require('ng-server-time');
   
   io.sockets.on('connection', function (socket) {
     server_time.init(socket);
   });

###Usage

app.controller('MainController', function($scope, ServerTime){
    // Date.now() on the server
    $scope.now = ServerTime.now();

    // new Date() on the server
    $scope.new = ServerTime.new();

    // get offset in milliseconds between current browser
    // time and server time
    $scope.getOffset = ServerTime.getOffset();
});
