但我收到了这个错误：
Fatal error: Uncaught exception 'Exception' with message 'DateTimeZone::__construct() [<a href='function.DateTimeZone---construct'>function.DateTimeZone---construct</a>]: Unknown or bad timezone (Asia/Kolkata)
Fatal error: Uncaught exception 'Exception' with message 'DateTimeZone::__construct() [<a href='function.DateTimeZone---construct'>function.DateTimeZone---construct</a>]: Unknown or bad timezone (Asia/Kolkata)
Though it works well for Asia/Daccafor example. What could be the problem and how to fix it?

I tried your example and it worked for me with PHP 5.3.1 and "Olson" Timezone Database Version 2009.18.
我试过你的例子，它对我有用PHP 5.3.1 和 "Olson" Timezone Database Version 2009.18。
You should do a phpinfo()and see what time zone DB version you have and if it's older update it. You can see in this listthat the most recent version, 2011.1, has Asia/Kolkata.
你应该做一个phpinfo()看看你有什么时区数据库版本，如果它是旧的更新它。您可以在此列表中看到最新版本 2011.1 包含 Asia/Kolkata。

Try this for fun.
试试这个很有趣。
$timezones = array('Europe/London', 'Mars/Phobos', 'Asia/Kolkata');
foreach ($timezones as $tz) {
try {
$mars = new DateTimeZone($tz);
} catch(Exception $e) {
echo $e->getMessage() . '<br />';
}
}

I've got same problem when try to run webserver in CHROOT jail. In this case chrooted dir can not contain Linux timezone files. If it's your case and you have access to webserver files simple copy all files to chroot jail:
尝试在 CHROOT jail 中运行网络服务器时，我遇到了同样的问题。在这种情况下，chrooted 目录不能包含 Linux 时区文件。如果这是您的情况并且您可以访问网络服务器文件，只需将所有文件复制到 chroot jail：
For CentOS it's
对于 CentOS，它是
cp -R /usr/share/zoneinfo/ /MY_CHROOT_DIR/usr/share/
