@leah I knew that europe and the us switch times at different moments in the calendar, but it didn't really sink in to me how much it means that a *meeting itself* (if it is to recur "at the same time") must have a notion of which tz it belongs to. This feels like something something mumble holonomy around vector bundles or something. "If you are to compare whether two times of day are the same time, you must actually transport one and then compare."
