问题描述

在PHP中是否可以获取给定位置的时区偏移量?例如.当指定位置悉尼/澳大利亚"时，将时区偏移量设置为"+1100".对于该功能，奖励是牢记夏令时(即知道夏令时并根据其调整偏移量).

Is it possible in PHP to get the timezone offset for a given location? E.g. when given the location "Sydney/Australia" to get the timezone offset as "+1100". Bonus would be for this function the keep daylight savings in mind (i.e. it's aware of daylight savings and adjusts the offset according).

推荐答案

要显示本地日期/时间，可以使用以下内容，其中欧洲/柏林"将替换为用户的时区.

To display a local date/time you can use the following, where 'Europe/Berlin' would be replaced with the user's timezone.

$date = new DateTime($value);
$date->setTimezone(new DateTimeZone('Europe/Berlin'));
echo $date->format('Y-m-d H:i:s');
