Recurrence.Range.StartDate / EndDate contain timezone offset

问题

Recurrence rule dates contain timezone offset where the calendar event "Start" / "End" fields are in UTC which seems incorrect behavior (Bug?). Did anyone knows why the "Recurrence.Range" "StartDate" / "EndDate" fields contains dates which are not UTC? Expected behavior is to receive UTC dates for all date fields in the calendar event object.

I'm currently working on integration between Office365 calendar events and third-party client-side Scheduler widgets (which supports only iCal recurrence rule) and doesn't know how to interpret correctly the above dates in recurrence "Range" object.

This appears to be a bug in the API. We have a work item to investigate and fix it, but I don't have any timeframes to share.
