Can you imagine how much more difficult that would be to program for? Instead of (relatively) easy to parse timezone rules you have some kind of awful, locale specific agreement that that event you scheduled for 9am monday every week would actually occur at 8am half of the year?

I'm not sure if you are serious, but I don't understand what you think would be involved. If you remove the time inconsistencies from a calendar, any decent calendaring app will solve the scheduling problem you are left with. Scheduling is a data entry problem. It is a problem we have with or without timezones and dst changes.
