Is there a way to make the iPhone's Calendar App support timezones with appointments, or is there an alternative App that has multiple timezone support? I have a friend with an iPhone 4 (4.2.1) who travels around quite a bit and always struggles to book appointments with people when he's outside of his home country, the U.S.
The conversation might go something like this:
[The scene is a New Zealand Beach on a Sunny January 5th]
"Let's met for lunch a 2pm, sushi, my shout"
"Sweet, so, 2pm new zealand time is 12pm yesterday american time, so I'll put it in my iCal at 12pm yesterday"
He needs iCal to be smart enough to adjust to the timezone of the country he is in. His iPhone does figure out local time from his telco and adjust that when he enters a new country.
