   * the time zone settings of the machine where the code is running.
   *
   * @param {number} offset Offset of the *desired* timezone in hours (fractions will be honored)
   * @param {(number|string)} timestamp Timestamp representing the desired time in *UTC*
   *
   * @example
   * !!!! WARNING !!!!!
   * This is not a complete Date object so only methods that were implemented can be called safely.
   * To make matters worse, TzDate instances inherit stuff from Date via a prototype.
   *
   * We do our best to intercept calls to "unimplemented" methods, but since the list of methods is
   * incomplete we might be missing some non-standard methods. This can result in errors like:
   * "Date.prototype.foo called on incompatible Object".

  /**
   * @ngdoc service
   * @name $httpBackend
   * @description
   * Fake HTTP backend implementation suitable for unit testing applications that use the
   * {@link ng.$http $http service}.
   *
   * *Note*: For fake HTTP backend implementation suitable for end-to-end testing or backend-less
   * development please see {@link ngMockE2E.$httpBackend e2e $httpBackend mock}.
   *
   * During unit testing, we want our unit tests to run quickly and have no external dependencies so
   * we don’t want to send [XHR](https://developer.mozilla.org/en/xmlhttprequest) or
   * [JSONP](http://en.wikipedia.org/wiki/JSONP) requests to a real server. All we really need is
   * to verify whether a certain request has been sent or not, or alternatively just let the
   * application make requests, respond with pre-trained responses and assert that the end result is
   * what we expect it to be.
   *
   * This mock implementation can be used to respond with static or dynamic responses via the
   * `expect` and `when` apis and their shortcuts (`expectGET`, `whenPOST`, etc).
   *
   * When an Angular application needs some data from a server, it calls the $http service, which
   * sends the request to a real server using $httpBackend service. With dependency injection, it is
   * easy to inject $httpBackend mock (which has the same API as $httpBackend) and use it to verify
   * the requests and respond with some testing data without sending a request to a real server.
   *
   * There are two ways to specify what test data should be returned as http responses by the mock
   * backend when the code under test makes http requests:
   *
   * - `$httpBackend.expect` - specifies a request expectation
   * - `$httpBackend.when` - specifies a backend definition
   *
   *
   * # Request Expectations vs Backend Definitions
   *
   * Request expectations provide a way to make assertions about requests made by the application and
   * to define responses for those requests. The test will fail if the expected requests are not made
   * or they are made in the wrong order.
   *
   * Backend definitions allow you to define a fake backend for your application which doesn't assert
   * if a particular request was made or not, it just returns a trained response if a request is made.
   * The test will pass whether or not the request gets made during testing.
   *
   *
   * <table class="table">
   *   <tr><th width="220px"></th><th>Request expectations</th><th>Backend definitions</th></tr>
   *   <tr>
   *     <th>Syntax</th>
   *     <td>.expect(...).respond(...)</td>
   *     <td>.when(...).respond(...)</td>
   *   </tr>
   *   <tr>
   *     <th>Typical usage</th>
   *     <td>strict unit tests</td>
   *     <td>loose (black-box) unit testing</td>
   *   </tr>
   *   <tr>
   *     <th>Fulfills multiple requests</th>
   *     <td>NO</td>
   *     <td>YES</td>
   *   </tr>
   *   <tr>
   *     <th>Order of requests matters</th>
   *     <td>YES</td>
   *     <td>NO</td>
   *   </tr>
   *   <tr>
   *     <th>Request required</th>
   *     <td>YES</td>
   *     <td>NO</td>
   *   </tr>
   *   <tr>
   *     <th>Response required</th>
   *     <td>optional (see below)</td>
   *     <td>YES</td>
   *   </tr>
   * </table>
   *
   * In cases where both backend definitions and request expectations are specified during unit
   * testing, the request expectations are evaluated first.
   *
   * If a request expectation has no response specified, the algorithm will search your backend
   * definitions for an appropriate response.
   *
   * If a request didn't match any expectation or if the expectation doesn't have the response
   * defined, the backend definitions are evaluated in sequential order to see if any of them match
   * the request. The response from the first matched definition is returned.
   *
   *
   * # Flushing HTTP requests
   *
   * The $httpBackend used in production always responds to requests asynchronously. If we preserved
   * this behavior in unit testing, we'd have to create async unit tests, which are hard to write,
   * to follow and to maintain. But neither can the testing mock respond synchronously; that would
   * change the execution of the code under test. For this reason, the mock $httpBackend has a
   * `flush()` method, which allows the test to explicitly flush pending requests. This preserves
   * the async api of the backend, while allowing the test to execute synchronously.
   *
   *
   * # Unit testing with mock $httpBackend
   * The following code shows how to setup and use the mock backend when unit testing a controller.
   * First we create the controller under test:
   *
    ```js
    // The controller code
    function MyController($scope, $http) {
      var authToken;
  
      $http.get('/auth.py').success(function(data, status, headers) {
        authToken = headers('A-Token');
        $scope.user = data;
      });
  
      $scope.saveMessage = function(message) {
        var headers = { 'Authorization': authToken };
        $scope.status = 'Saving...';
  
        $http.post('/add-msg.py', message, { headers: headers } ).success(function(response) {
          $scope.status = '';
        }).error(function() {
          $scope.status = 'ERROR!';
        });
      };
    }
    ```
   *
   * Now we setup the mock backend and create the test specs:
   *
    ```js
      // testing controller
      describe('MyController', function() {
         var $httpBackend, $rootScope, createController;
  
         beforeEach(inject(function($injector) {
           // Set up the mock http service responses
           $httpBackend = $injector.get('$httpBackend');
           // backend definition common for all tests
           $httpBackend.when('GET', '/auth.py').respond({userId: 'userX'}, {'A-Token': 'xxx'});
  
           // Get hold of a scope (i.e. the root scope)
           $rootScope = $injector.get('$rootScope');
           // The $controller service is used to create instances of controllers
           var $controller = $injector.get('$controller');
  
           createController = function() {
             return $controller('MyController', {'$scope' : $rootScope });
           };
         }));
  
  
         afterEach(function() {
           $httpBackend.verifyNoOutstandingExpectation();
           $httpBackend.verifyNoOutstandingRequest();
         });
  
  
         it('should fetch authentication token', function() {
           $httpBackend.expectGET('/auth.py');
           var controller = createController();
           $httpBackend.flush();
         });
  
  
         it('should send msg to server', function() {
           var controller = createController();
           $httpBackend.flush();
  
           // now you don’t care about the authentication, but
           // the controller will still send the request and
           // $httpBackend will respond without you having to
           // specify the expectation and response for this request
  
           $httpBackend.expectPOST('/add-msg.py', 'message content').respond(201, '');
           $rootScope.saveMessage('message content');
           expect($rootScope.status).toBe('Saving...');
           $httpBackend.flush();
           expect($rootScope.status).toBe('');
         });
  
  
         it('should send auth header', function() {
           var controller = createController();
           $httpBackend.flush();
  
           $httpBackend.expectPOST('/add-msg.py', undefined, function(headers) {
             // check if the header was send, if it wasn't the expectation won't
             // match the request and the test will fail
             return headers['Authorization'] == 'xxx';
           }).respond(201, '');
  
           $rootScope.saveMessage('whatever');

   *
   * As opposed to unit-testing, in an end-to-end testing scenario or in scenario when an application
   * is being developed with the real backend api replaced with a mock, it is often desirable for
   * certain category of requests to bypass the mock and issue a real http request (e.g. to fetch
   * templates or static files from the webserver). To configure the backend with this behavior
   * use the `passThrough` request handler of `when` instead of `respond`.
   *
   * Additionally, we don't want to manually have to flush mocked out requests like we do during unit
   * testing. For this reason the e2e $httpBackend automatically flushes mocked out requests
   * automatically, closely simulating the behavior of the XMLHttpRequest object.
   *
   * To setup the application to run with this http backend, you have to create a module that depends
   * on the `ngMockE2E` and your application modules and defines the fake backend:
   *
   * ```js
   *   myAppDev = angular.module('myAppDev', ['myApp', 'ngMockE2E']);
   *   myAppDev.run(function($httpBackend) {
   *     phones = [{name: 'phone1'}, {name: 'phone2'}];
   *
   *     // returns the current list of phones
   *     $httpBackend.whenGET('/phones').respond(phones);
   *
   *     // adds a new phone to the phones array
   *     $httpBackend.whenPOST('/phones').respond(function(method, url, data) {
   *       var phone = angular.fromJson(data);
   *       phones.push(phone);
   *       return [200, phone, {}];
   *     });
   *     $httpBackend.whenGET(/^\/templates\//).passThrough();
   *     //...
   *   });
   * ```
   *
   * Afterwards, bootstrap your app with this new module.

     * @description
     *
     * *NOTE*: This function is also published on window for easy access.<br>
     *
     * The inject function wraps a function into an injectable function. The inject() creates new
     * instance of {@link auto.$injector $injector} per test, which is then used for
     * resolving references.
     *
     *
     * ## Resolving References (Underscore Wrapping)
     * Often, we would like to inject a reference once, in a `beforeEach()` block and reuse this
     * in multiple `it()` clauses. To be able to do this we must assign the reference to a variable
     * that is declared in the scope of the `describe()` block. Since we would, most likely, want
     * the variable to have the same name of the reference we have a problem, since the parameter
     * to the `inject()` function would hide the outer variable.
     *
     * To help with this, the injected parameters can, optionally, be enclosed with underscores.
     * These are ignored by the injector when the reference name is resolved.
     *
     * For example, the parameter `_myService_` would be resolved as the reference `myService`.
     * Since it is available in the function body as _myService_, we can then assign it to a variable
     * defined in an outer scope.
     *
     * ```
     * // Defined out reference variable outside
     * var myService;
     *
     * // Wrap the parameter in underscores
     * beforeEach( inject( function(_myService_){
     *   myService = _myService_;
     * }));
     *
     * // Use myService in a series of tests.
     * it('makes use of myService', function() {
     *   myService.doStuff();
     * });
     *
     * ```
     *
     * See also {@link angular.mock.module angular.mock.module}
     *
     * ## Example
     * Example of what a typical jasmine tests looks like with the inject method.
     * ```js
     *
     *   angular.module('myApplicationModule', [])
     *       .value('mode', 'app')
     *       .value('version', 'v1.0.1');
     *
     *
     *   describe('MyApp', function() {
     *
     *     // You need to load modules that you want to test,
     *     // it loads only the "ng" module by default.
     *     beforeEach(module('myApplicationModule'));
     *
     *
     *     // inject() is used to inject arguments of all given functions
     *     it('should provide a version', inject(function(mode, version) {
     *       expect(version).toEqual('v1.0.1');
     *       expect(mode).toEqual('app');
     *     }));
     *
     *
     *     // The inject and module method can also be used inside of the it or beforeEach
     *     it('should override a version and test the new version is injected', function() {
     *       // module() takes functions or strings (module aliases)
     *       module(function($provide) {
     *         $provide.value('version', 'overridden'); // override version here
     *       });
     *
     *       inject(function(version) {

     *       });
     *     });
