php教程设置北京时间函数date_default_timezone_set()
定义和用法
date_default_timezone_set() 函数设置用在脚本中所有日期/时间函数的默认时区。

语法
date_default_timezone_set(timezone)

$now = time();
date_default_timezone_set('america/new york');
print date('c', $now);
date_default_timezone_set('europe/paris');
print date('c', $now);
?>

再看一个例子

date_default_timezone_set('america/denver');

$summer = mktime(12,0,0,7,4,2008);
print date('c', $summer) . "n";

date_default_timezone_set('america/phoenix');
print date('c', $summer) . "n";
?>

注释:自 php 5.1.0 起(此版本日期时间函数被重写了),如果时区不合法则每个对日期时间函数的调用都会产生一条 e_notice 级别的错误信息,如果使用系统设定或 tz 环境变量则还会产生 e_strict 级别的信息。
