php系统时区设置方法总结

date.timezone = Asia/Shanghai

php_value date.timezone Asia/Shanghai
SetEnv TZ Asia/Shanghai

1 date_default_timezone_set('Asia/Shanghai');//'Asia/Shanghai'   亚洲/上海

2 date_default_timezone_set('Asia/Chongqing');//其中Asia/Chongqing'为“亚洲/重庆”

3 date_default_timezone_set('PRC');//其中PRC为“中华人民共和国”

4i ni_set('date.timezone','Etc/GMT-8');

5 ini_set('date.timezone','PRC');

6 ini_set('date.timezone','Asia/Shanghai');

7 ini_set('date.timezone','Asia/Chongqing');

date_default_timezone_set('PRC');

//PRC为中华人民共和国时区

<?php
    date_default_timezone_set("Asia/Kolkata");
    echo date('d-m-Y H:i:s'); //Returns IST
?>

<?php
echo "UTC时间：".date("Y-m-d H:i:s");  //显示默认的UTC时间
date_default_timezone_set("PRC");      //使用中华人民共和国的时区
echo "<br>";
echo "北京时间：".date("Y-m-d H:i:s");  //输出北京时间
echo "<br>";
echo "中文时间：".date("Y年m月d日 H时i分s秒");  //输出中文格式时间
echo "<br>";
echo "当前时区：".date_default_timezone_get();   //获取当前时区
?>

代码
date_default_timezone_set(‘Etc/GMT’);
//在输出时间之前设置时区，Etc/GMT为时间标准时间
echo(time());
echo(‘
’);
echo date(‘Y-m-d H:i:s’, time());
echo(‘
’);
echo gmdate (“Y-m-d H:i:s”, time());
echo(‘
’);
date_default_timezone_set(‘PRC’);
//在输出时间之前设置时区，PRC为中华人民共和国
echo(time());
echo(‘
’);
echo date(‘Y-m-d H:i:s’, time());
echo(‘
’);
echo gmdate (“Y-m-d H:i:s”, time());
?>
结果：
1276257131
2010-06-11 11:52:11
2010-06-11 11:52:11
1276257131
2010-06-11 19:52:11
2010-06-11 11:52:11
结论：
time() ：标准时间戳
指返回自从 Unix 纪元（格林威治时间 1970 年 1 月 1 日 00:00:00）到当前时间（指的是当前GMT标准时间）的秒数，它的值跟php系统设置的时区无关。
date():返回的是当前 GMT标准时间的本地化时间的“自定义格式”时间，跟php系统设置的时区有关。
gmdate():返回的是当前 GMT标准时间的“自定义格式”时间，跟php系统设置的时区无关

unix时间戳：指的是当前（GMT标准）时间离unix纪元时间（1970-01-01 00:00:00）的秒数；
代码
date_default_timezone_set(‘Etc/GMT’);
//在输出时间之前设置时区，Etc/GMT为时间标准时间
echo(strtotime(’1970-01-01 08:00:00′));
echo(‘
’);
date_default_timezone_set(‘PRC’);
//在输出时间之前设置时区，PRC为中华人民共和国
echo(strtotime(’1970-01-01 08:00:00′));
?>
