It’s very simple, I only put the key code

<p ng-controller="myCtrl">
<input type="text" ng-model="clock.now"></p>


function myCtrl($scope,$timeout){
$scope.clock = {
    now : new Date()
}
var updateClock = function(){
    $scope.clock.now = new Date() ;
}
//$timeout(function(){
setInterval(function(){    
    updateClock()
    $scope.$apply()
},1000)
updateClock();

}

You can use setInterval, but not $timeout. Why?
