I don't understand the described result for Option 1 or how having stored in UTC creates a problem there. It would seem to me like when the government changes the rules for local time, they are effectively moving the (real, not clock) time for the conference. It would seem like there is enough information stored in the database that installing the new time zone rules should cause the timer to move to accommodate this, as long as addresses don't get redefined (a different issue with that storage model). I don't see why the timer would not instantaneously jump an hour to correct itself when it becomes aware of the new rules or why it wouldn't hit the zero at the right time.
