OK, noted and look forward to the fix.
I can add to this now in as much as I have found a workaround. You have to go to the first instance of a recurring event after the time flip has occurred (e.g. 30th October 2016) then from the admin bar go to “Edit Events/Edit Future Events”. This splits the event into two and all you need to do is check and re-enter the correct times as appropriate and hit Update.
It’s not ideal since it needs manual intervention twice a year but it does work. Might help someone out there who has the same problem. I found that making the timezone visible is helpful.
