php将datetime转换为UTC(php convert datetime to UTC)

php将datetime转换为UTC(php convert datetime to UTC)

我需要一个简单的方法来将日期时间戳转换为UTC（从服务器的任何时区）HOPEFULLY而不使用任何库。

I am in need of an easy way to convert a date time stamp to UTC (from whatever timezone the server is in) HOPEFULLY without using any libraries.

最满意答案

尝试getTimezone和setTimezone ，参见示例

（但这确实使用了一个类）

更新：

没有任何课程，你可以尝试这样的事情：

$the_date = strtotime("2010-01-19 00:00:00"); echo(date_default_timezone_get() . "<br />"); echo(date("Y-d-mTG:i:sz",$the_date) . "<br />"); echo(date_default_timezone_set("UTC") . "<br />"); echo(date("Y-d-mTG:i:sz", $the_date) . "<br />");

注意：您可能需要将时区设置为原始设置

Try the getTimezone and setTimezone, see the example

(But this does use a Class)

UPDATE:

Without any classes you could try something like this:

$the_date = strtotime("2010-01-19 00:00:00"); echo(date_default_timezone_get() . "<br />"); echo(date("Y-d-mTG:i:sz",$the_date) . "<br />"); echo(date_default_timezone_set("UTC") . "<br />"); echo(date("Y-d-mTG:i:sz", $the_date) . "<br />");

NOTE: You might need to set the timezone back to the original as well
