javascript - Fullcalendar wrong time in on click event - Stack Overflow

I'm using angular and fullcalendar. I have (surprise) timezone-issues, and I can't seem to get it right.

If in the weekview I click on 08.00 hours, I open a modal and show the time, I see 09.00 hours.

timezone: "Europe/Brussels",
ignoreTimezone: false,

This is (atm) a +0100 timezone, and during summer a +0200 timezone

The click-event:

dayClick: function (date, jsEvent, view) {

    $scope.newEventDate = date;

    var modalInstance = $modal.open({
        templateUrl: 'newRosterEvent',
        controller: 'NewEventModalController',
        backdrop: "true",
        resolve: {
            event: function () {
                       return $scope.newEventDate;
                   },
            stage: function () {
                       return $scope.stage;
                   }
            }
       });

To display the time:

stagewebApp.controller('NewEventModalController', ["$scope", "$modalInstance","$filter", "event", "stage", function ($scope, $modalInstance, $filter,event, stage) {

    $scope.stage = stage;

    $scope.day = new Date($filter('date')(event._d, "yyyy-MM-dd"));

    $scope.start = event.toDate();

    ....more code....
}

In this case $scope.start displays the clicked time +1

So it seems that fullcalendar takes the time I clicked and converts it to the timezone selected, but I would expect it to interpret the clicked time as being in the timezone I selected.

Apparently I am tackling this wrong, so what is the correct way to do this? ( $scope.start should show the time I clicked (preferably in my timezone)). Afterwards I send it to the server where it is stored as UTC.

The current version of FullCalendar uses moment.js extensively. The problems you are describing are from improper use of moment objects. Specifically:

$scope.start = event.toDate();

When you call toDate, you get back a regular JavaScript Date object - which will be based on the same UTC instant, but will always take on the behavior of the time zone where the code is running. You have a few options:

• You can keep it as a moment object:

  $scope.start = event;
  

• You can format it to an ISO string that retains the time zone offset:

  $scope.start = event.format(); // ex: '2015-03-04T08:00:00+01:00'
  

With either option, you'll need to follow through with the usage of $scope.start to expect either a moment or a string, rather than a Date.

Also, in this code:

$scope.day = new Date($filter('date')(event._d, "yyyy-MM-dd"));

You should never access the _d property directly, as there can be unintended side-effects. Consider the underscore to mean "internal". Also, you don't need Angular's date filter here since moment objects have formatting capabilities. Instead, just do this:

$scope.day = event.format("YYYY-MM-DD");
