Exactly. Sweden, for example, switches several weeks before the US in the fall and spring leading to a bizarre situation where the two countries are only X-1 hours apart instead of X hours. It has the strange (but sensical) effect of also moving meetings by one hour on Swedish calendars. But only meetings that were created by Americans! If the meeting was created by a Swede it moves one hour on the American calendar. This inevitably leads to some confusion. So we already have this problem, whether or not there is DST or not won’t really make it worse.
