As far as I can tell, it is all behaving correctly now. Is there an event or two you could give me as an example? Tell me what time/timezone you want it to display and what you have it set too. I'm looking at your calendar now and I'm pretty sure it's correct, logged in and out. Apologies for the inconvenience.
In the future when something like this happens, you can always try a hard refresh in your browser to try to force it to update cache. That is my guess as to why you saw the incorrect time after I had fixed it the other day, that it was an old cache with the old time still. Using hard refresh can be useful for all kinds of stuff all over the internet as well haha.
