Scheduling a recurring meeting of busy people (think college students with busy schedules) across continents, cultures and countries is hard enough without time

Scheduling a recurring meeting of busy people (think college students with busy schedules) across continents, cultures and countries is hard enough without timezones and arbitrary changes in daylight savings time. For example, Dubai doesn't have DST - it never changes relative to the others. Kosovo and Croatia change a week before the U.S. changes. Then the U.S. changes but Dubai doesn't. For about 6 weeks out of the year, scheduling is confusing chaos, and a workable schedule under one time configuration very likely doesn't work for the others, keeping in mind that a midday meeting in the U.S. is pushing on midnight in Dubai and family time in central Europe. The whole situation is a disaster, and while manageable, certainly takes a lot of effort, planning, and luck to get right.
