Make Calendar understand flight times across time zones?
Whenever I fly between time zones, I like to enter enter my departure and arrival times into my calendar using local time. Unfortunately, this means that sometimes my ending time for the flight will be earlier than the starting time, and Calendar doesn't seem to like time traveling.
I've turned on time zone support and I see an option called "floating" time zone, which I think may be the answer, but every time I select it it just snaps back to one of the other time zones. Anyone know how to get these sorts of flight times into Calendar?
