This is one of the most valuable iPhone app for me.
As you know, iPhones default clock shows current time and date in various locations. But when I want to know the time in other countries at specific time in my city, I have to do the complicated math in my head... And I found this iTimeZone. It works like a charm. Ive just bought it a few days ago, and I already cannot do my job without it.
Every day I work closely with offices scattered around the world, and I was having a hard time to figure out "what time should I start a conference call with NY, Paris and Beijing without forcing everybody to attend the call at ridiculous time?" But since I obtained iTimeZone, voila! I can find an appropriate time window in a few seconds.
Dear developer, thank you very very much for creating iTimeZone. In the future version though, please let me change the current location instantly, so that I can find time and date in city X relative to a city other than my current location. Also, as other reviewers pointed out, please embed iTimeZones own list of cities, instead of using iPhones incomplete city list.
