from my point of few its the other way around. There are very few applications that need to schedule events into the future, and that is literally the only situation where you have to worry about the timezone. Btw, keeping the timezone is insufficient as well if you're building a calendar/scheduler. If the user changes the timezone after scheduling the event... do you keep to the old one and alert him whenever, or do you adjust? There are a lot of edge cases with schedulers -- yet as i said before, most applications don't schedule into the future. They're mostly just doing things right now or within the next few minutes and keeping a log of their actions.
