php - Is there a difference between Europe/London and UTC in PHP?

Question

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

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

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

Answer 1

如何用 PHP 解释欧洲/伦敦？基本上是UTC / GMT吗？

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：

$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
