Let's say I have two dates:
2015-11-13T08:00:00 and 2015-11-13T10:00:00 , as you can see there is a difference of two hours between these dates. I would like to put a timer in my view that shows this difference.
I tried to adapt this example: link .
However when the change it stops working.
How do I start this timer, or where do I begin?
I've created a directive in Angular JS for this:
angular.module('iCountdown', [])
.directive("iCountdown", function () {
return {
restrict: "EAC",
scope: {
setStartDate: "@",
setEndDate: "@",
expireMessage: "@",
startMessage: "@",
formatView: "@",
setTemplateView: "@",
consideredCurrentDate: "@",
},
replace: true,
template: "<div><div></div></div>",
link: function (scope, element) {
var insertDate = function() {
scope.setMessageExpired(scope.expireMessage);
scope.setMessageInitial(scope.startMessage);
if (angular.isDefined(scope.setStartDate) && angular.isDefined(scope.setEndDate)) {
params.dateStart = scope.setStartDate;
params.dateEnd = scope.setEndDate;
if (angular.isDefined(scope.setTemplateView)) {
params.templateView = scope.setTemplateView;
params.activeCurrentDate = scope.consideredCurrentDate;
}
}
scope.start();
};
scope.$watch('setDateEnd', function() {
insertDate();
}, true);
var _end = new Date();
var _start = new Date();
var _second = 1000;
var _minute = _second * 60;
var _hour = _minute * 60;
var _day = _hour * 24;
var params = {

format:'Y-m-d H:i:s',
dateEnd: null,

};
scope.getCurrentStartDate = function() {
var _dt = new Date();

The directive in HTML:
<div ng-app="iCountdown">
<i-countdown set-start-date="2015-11-13 10:58:00"
set-end-date="2015-11-13 13:18:00"
format-view="%d dias %h hs %i min %s sg"
expire-message="Fim de jogo"
start-message="Aguarde o início"
considered-current-date="true"
set-template-view="<div id='elemento'>%t</div>">
</i-countdown>
</div>
