As a result, my events from Org are shown at the wrong time in Google calendar. Secondly, it seems to me that the concept of having a timezone for the whole .ics file might be wrong. My Org files have dated events in both the summer and the winter, and it is obvious to me that the times for the summer events should be understood as British Summer time (UTC+1), and that the times for the winter events should be understood as GMT (UTC). Do others agree with that? If so, it would need to be reflected on export by each event having its own timezone, instead of a global timezone for the whole file. Best wishes, Neil
