Maybe I'm doing it wrong but I have TZS turned off and, my items to my calendar based on my home time zone and if need be adjust the time on an out of time event to correspond to my current time zone so that when I arrive at the new time zone, the even is at the correct time (i.e. i have a mtg in NY at 3pm so I enter it on my calendar as noon and when I arrive in NY, it adjusts itself to 3pm). The one thing I don't adjust however is flight information/itineraries as I download those from United and they default my home time zone and change accordingly when I travel
