Can I show date in local time zone while save date in UTC?

Question

我想在本地时区显示日期，但是我已经在UTC中保存了日期，因此可以使用php在本地时区显示日期。

Answer 1

PHP's strtotime function will interpret timezone codes, like UTC. If you get the date from the database/client without the timezone code, but know it's UTC, then you can append it.

Assuming you get the date with timestamp code (like "Fri Mar 23 2012 22:23:03 GMT-0700 (PDT)", which is what Javascript code ""+(new Date()) gives):

$time = strtotime($dateWithTimeZone);
$dateInLocal = date("Y-m-d H:i:s", $time);

Or if you don't, which is likely from MySQL, then:

$time = strtotime($dateInUTC.' UTC');
$dateInLocal = date("Y-m-d H:i:s", $time);

Alternatively

date() and localtime() both use the local timezone for the server unless overridden; you can override the timezone used with date_default_timezone_set() .
