php将日期时间转换为UTC

2022-01-16 00:00:00 datetime timezone utc php

我需要一种简单的方法来将日期时间戳转换为 UTC(从服务器所在的任何时区)，希望不使用任何库.

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.

推荐答案

试试 getTimezone 和 setTimezone，见例子

(但这确实使用了一个类)

(But this does use a Class)

更新:

没有任何课程，你可以尝试这样的事情:

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 />");

注意:您可能还需要将时区设置回原始时区

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