Answer 1

Since you are using input type as date, the string in model should be compatible with Date object in javascript. So you can do

var timestamp = new Date($scope.startDate).getTime()

Answer 2

To use in a controller you can do something like this:

myApp.controller('TimestampCtrl', ['$scope', function($scope) {
  $scope.toTimestamp = function(date) {
    var dateSplitted = date.split('-'); // date must be in DD-MM-YYYY format
    var formattedDate = dateSplitted[1]+'/'+dateSplitted[0]+'/'+dateSplitted[2];
    return new Date(formattedDate).getTime();
  };
}]);

And can be used like this:

<div ng-controller="TimestampCtrl">
  The timestamp of <input ng-model="date"> is {{ toTimestamp(date) }}
</div>

Answer 3

Use a directive to change the value from view to model.

angular.module('app', [])
    .directive('stringToTimestamp', function() {
        return {
            require: 'ngModel',
            link: function(scope, ele, attr, ngModel) {
                // view to model
                ngModel.$parsers.push(function(value) {
                    return Date.parse(value);
                });
            }
        }
    });
