Angularjs $viewValue without changing $modelValue -


in angular (1.4.x), there way dynamically change input context without changing $modelvalue? example: possible dynamically toggle time (moment) input text/content local/utc without changing $modelvalue. here's example change both view , model values. need mask input context , not model value.

thanks! 

var app = angular.module('testparser', []);    app.controller('mainctrl', function($scope) {    $scope.data = {      name: ''    };  });  app.directive('changetime', function() {    return {      restrict: 'ea',      require: 'ngmodel',      link: function(scope, element, attrs, ngmodel) {        //format text going user (model view)        ngmodel.$formatters.push(function(value) {          return value;        });          //format text user (view model)        ngmodel.$parsers.push(function(value) {          return value;        });          scope.data.time = moment().format('hh:mm:ss')        scope.setlocaltime = function() {          scope.data.time = moment().local().format('hh:mm:ss');        }        scope.setutctime = function() {          scope.data.time = moment().utc().format('hh:mm:ss');        }      }    }  });
<html ng-app="testparser">    <head>    <meta charset="utf-8" />    <script data-require="angular.js@1.4.8" data-semver="1.4.8" src="https://code.angularjs.org/1.4.8/angular.js"></script>    <script data-require="moment.js@*" data-semver="2.10.2" src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.10.2/moment.min.js"></script>      </head>    <body ng-controller="mainctrl">    <input type="button" value="set local" ng-click="setlocaltime()" />    <input type="button" value="set utc" ng-click="setutctime()" />    <input changetime ng-model="data.time" />    <pre>model is: {{data.time}}</pre>  </body>    </html>
