ng-server-time

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

##Installation

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

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

• 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;
  });
  

• 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>
  

• 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();
});
