Appointment creation with a timezone offset

[Chitra]

I am using the rad scheduler with a exchange service provider, i have time zone offset value set for the scheduler and the display of appointments work fine. However when i create appointment with the offset i am getting an error:
The request failed schema validation: The 'http://schemas.microsoft.com/exchange/services/2006/types:BaseOffset' element is invalid - The value '-PT-8H' is invalid according to its datatype 'http://www.w3.org/2001/XMLSchema:duration' - The string '-PT-8H' is not a valid Duration value.

Looking through the documentation i found that the appointment time needs to be convered to UTC. So i added the following line in the appointment Inset event.

e.Appointment.Start.ToUniversalTime();
e.Appointment.End.ToUniversalTime();

While stepping thru the code the start and end times look ok, meaning they are in UTC however i get the error above
at Exchange\ExchangeSchedulerProvider.cs:line 166
       at Telerik.Web.UI.SchedulerProviderBase.Insert(ISchedulerInfo schedulerInfo, Appointment appointmentToInsert)
when trying to create the item.

Can you please help?

Hi Chitra,

Could you, please, try to assign the values, not only to call the method ToUniversalTime(), e.g. like the following:

e.Appointment.Start = e.Appointment.Start.ToUniversalTime();
e.Appointment.End = e.Appointment.End.ToUniversalTime();

I was experiencing this problem as well. The problem occurs when there's a negative offset in the time zone. The proper format should be -PT8H and not -PT-8H. What I did to fix this was to modify the ExchangeSchedulerProvider.cs (line 337) by putting Math.Abs() to the tzOffset.TotalHours value.See code:

tz.BaseOffset = String.Format("{0}PT{1}H", sign, (int)Math.Abs(tzOffset.TotalHours));

Hope this helps.
