Daylight Saving Time is not considered in the exception rule for recurring appointments

Hello Peter,
It will take us some time to research this case. I am going to update this thread as soon as possible. Meanwhile, I would like to clarify how you set up a time zone. Have you set the timeZone field directly or do you use the OS settings? Would you please also specify the exact time zone from the list that you are using.

By the way, it will be helpful if you send us the scheduler settings you are using and the data you use to generate an appointment? I hope to hear from you soon.

Hi Maxim,

Thanks.

I am using Australia/Canberra timezone.

Also, I am not setting any timezone, just using OS TZ settings.

Below are the scheduler settings

HTML
[dataSource]="calendarDisplayData" [views]="['day','week', 'month']" [currentDate]="currentDate" [currentView]="currentView"  
[height]="750" firstDayOfWeek="0" startDayHour=8 endDayHour=23 recurrenceRuleExpr="recurrenceRule" recurrenceExceptionExpr="recurrenceException"  
[showAllDayPanel]="false" [useDropDownViewSwitcher]="false" appointmentTemplate='appointment' crossScrollingEnabled="true"  
appointmentTooltipTemplate="appointment-tooltip" (onAppointmentAdding)="saveAppointment($event)" (onAppointmentUpdating)="updateAppointment($event)"  
(onAppointmentDeleting)="deleteAppointment($event)" (onAppointmentFormCreated)="addAssessmentAvailability($event)"  
(onAppointmentClick)="onAppointmentClick($event)" (onOptionChanged)="onOptionChanged($event)"  

Also, scheduler seems to behave weirdly.

1. Sometimes appointments are displayed on incorrect times, then upon the refreshing page, it gets corrected
2. If I open an existing appointment slot close it, then click scheduler to create new, the start time of that appointment is
       not correct ( It shows me start time of the previous appointment )
3. It is extremely complicated to customize the appointment create/update form.
4. The schedule is not mobile responsive.
5. If the number of appointments is higher, appointments get grouped, I don't have any option to customize the popup for such grouped appointment.

Thank you for your clarification, Peter.

Hi,
Do we have any update regarding the daylight time issue?

We are still working on it. Once we have any news, we will notify you.

Hello Peter,
Right now we are working on the date exception functionality to fully support different time zones.
At the same time, to check if your case can be fixed, we would like to ask you to change the following example

This will help us provide a more precise fix for you. I hope to hear from you soon.
