PHP中的欧洲/伦敦和UTC之间有区别吗? [英] Is there a difference between Europe/London and UTC in PHP?

问题描述

我知道 UTC 和 GMT 实际上是一回事.

I know that UTC and GMT are effectively the same thing.

BST(英国标准时间)为 GMT +- 1 小时，具体取决于 DST(夏令时).

BST (British Standard Time) is GMT +- 1 hour depending on DST (Daylight Saving Time).

考虑到这一点，Europe/London 在 PHP 中是如何解释的?基本上是UTC/GMT吗?

With that in mind, how is Europe/London interpreted in PHP? Is it basically UTC/GMT?

它们不一样(UTC/GMT 没有夏令时).在撰写本文时，它们相隔一个小时:

They are not the same (UTC/GMT has no daylight savings). As of this writing they are an hour apart:

$utc = new DateTime('now', new DateTimeZone('UTC'));
echo $utc->format('Y-m-d H:i:s'); // output: 2013-06-03 15:37:08

$el = new DateTime('now', new DateTimeZone('Europe/London'));
echo $el->format('Y-m-d H:i:s'); //  output: 2013-06-03 16:37:08
