I agree with Jon that this is not a U.S. problem only. It's global. I am located in Europe with time zone CET, and we just switched back an our from CEST last weekend, 25 October - but I manage Marketo programs in EMEA and APAC, so I'm conscious of all sorts of time differences and daylight savings when I work with the UK, Africa or ANZ. What I observed with my Australian colleagues: Two weeks ago I had an event scheduled in their AEDT (they switched from Standard to Daylight on 4 October), which back then was still in my CEST. So the time difference at that point was 9 hours, and my .ics file was set to 9:30 am CEST = 6:30pm AEDT. I assumed that when I switched to CET, my .ics file would be updated automatically, and the hour adjustment would show. But it didn't. My time zone went from displaying CEST to CET (which is good, as I understand other people don't experience that automatic switch in their time zones), but the actual scheduled time stayed the same. Due to that, my time difference all of a sudden was 10 hours, and my .ics file showed 9:30am CET = 7:30pm AEDT. This is very frustrating. I had to go through all programs where .ics files are in use and adjust them manually. And the worst: This weekend on 1 November my US colleagues on the East Coast go from EDT to EST and they have a lot more events and webinars running that need that manual adjustment, too. How come the time zone display adjusts, but not the set time?
