Issue with Daylight Saving Time (DTS) when i have to display some meetings

[terrenzio93]

Problem

Hi everyone! I have this kind of problem. Some meetings have correct start date and end date but, when the DTS comes or expires, they would get the wrong hour. I will show you some examples:

As you can see, this appointment starts at 10.30 and ends at 11.30 as it should be because it was saved with that particular start date/hour and end date/hour. But if I take another meeting in November, that is what is happening:

Even if in the DB we got the meeting starting at 6.00 and ending at 7.00, the calendar displays the wrong hour. I think that happen because of the DTS.

This has already been touched on here: https://github.com/nhn/tui.calendar/issues/423 Just log what offset u have and what time it should be and adjust the if-statement and the hours added or removed accordingly. var today=new Date(); if(today.getTimezoneOffset()===-60 && event.start._date.getTimezoneOffset()===0) { //We need to hack the time setting. We may need to still do this after end of BST as well. event.start.setHours(event.start.getHours()-2); event.end.setHours(event.end.getHours()-2); } ....rest of my event handler.... } Regards

Yes, It's a known issue as @FelixBrgn mentioned. It won't be easy to fix the issue. I hope to fix this issue with the release of the next major version. But there's no scheduled timeline for the release yet even we're working on it though.

Hi everybody. Thank you all for your time and your responses.

Here the solution I figured out thanked to your messages.

Solution

function getTimeTemplate(schedule, isAllDay) {
        var html = [];
        //console.log(schedule.start._date);
        //Bugfix ora legale ora solare, sia nel grid del calendario che nel primo popup informativo
        if(schedule.start._date.getTimezoneOffset()==-60){
            schedule.start._date.setHours(schedule.start.getHours()+1);     
            schedule.end._date.setHours(schedule.end.getHours()+1);         
        }

        if (!isAllDay) {
          html.push('<strong>' + moment(schedule.start.getTime()).format('HH:mm') + '</strong> ');
        }
        if (schedule.isPrivate) {
          html.push('<span class="calendar-font-icon ic-lock-b"></span>');
          html.push(' Private');
        } else {
          if (schedule.isReadOnly) {
            html.push('<span class="calendar-font-icon ic-readonly-b"></span>');
          } else if (schedule.recurrenceRule) {
            html.push('<span class="calendar-font-icon ic-repeat-b"></span>');
          } else if (schedule.attendees.length) {
            html.push('<span class="calendar-font-icon ic-user-b"></span>');
          } else if (schedule.location) {
            html.push('<span class="calendar-font-icon ic-location-b"></span>');
          }
          html.push(' ' + schedule.title);
        }

        return html.join('');
      }
