This is a problem on the Mac, iPhone, iPad and iCloud. I travel a lot, and I like to use the calendar to be able to keep my appointments. Unfortunately, there seems to be no way to turn off the feature that makes the times change as you change zones or cross the international date line. I'd like to be able to use a calendar in absolute time, without any regard to time zones. Whether timezone support is turned off or on, the times do change as i travel. I've reverted, quite some time ago, to using a paper calendar, simply because I can't rely on the Mac calendar to give me what I put in. Google, Microsoft, and everything else I've looked at has the same issue. If you put in an 8PM appointment in another timezone, when you go to that timezone, the time will change. If you put it in using that timezone, it will change to the timezone you're in when you're looking at it. I need to simply be able to look at the calendar and see where and what time I need to be there. I understand that many teleconference users use the timezone set up to their advantage and that's great, but why can't the rest of us have something that works? I'd sure appreciate some help or a point in the direction of a piece of software that actually will do this.
