OK, think this through. You're trying to find people in Iran who are posting on Twitter. How does finding all the people who have indicated a particular time zone help you? That time zone includes many countries. Remember, time zones are vertical... And even if it did, identifying people who SAY they are in that timezone by using their Twitter names is almost impossible. You would have to hack into Twitter and monitor the ISPs of people who post, as they post. Like Twitter wouldn't know when you do that?

This is another stupid piece of misinformation, like hiding people's user names, that lets people feel like they're part of what's happening in Iran. It just just encourages more people to clog up Twitter with useless, outdated, or completely wrong posts, pretending to be "where the action is".
