Hi Nathan - I've got the same problem and for the life of me I can't find a solution. It drives me nuts!!
At least once a week I find myself caught out because the time zone is out by an hour. (I'm in South Australia).
If I don't find a solution in the next couple of weeks I'll disconnect my Google Calendar and seriously consider going back to the free version of Evernote.
So, so freaking annoying!
Keep smiling - BB
