That's fine for logging; the problem is with scheduling future events. If someone schedules a meeting at (e.g.) noon next January, and between now and then the state that meeting takes place in switches from (e.g.) Eastern to Central time, then the program _must not_ move the meeting to eleven. Which means blindly storing the UTC or blindly storing a time+offset is inappropriate.
