如何使用DateTime对象设置时区？

Question

I made a code that print a log in a server folder, this log return also a date with hours but the server isn't in my Nation so the hours is incorrect for me. Actually this is my code:

$now = new DateTime();  
$aggiornata = "\r\n" . "Aggiornamento eseguito con successo per: " . $value['caption'] . " DATA: " . $now->format('d-m-Y H:i:s');
file_put_contents(getenv('OPENSHIFT_REPO_DIR').'php/log.txt', $aggiornata, FILE_APPEND);

How to set the correct hour for Italy?

Answer 1

看看DateTimeZone

$date = new DateTime('now',new DateTimeZone("Europe/Rome"));

Answer 2

您也可以在文件的顶部执行此操作，例如：

date_default_timezone_set('Europe/Rome');

Answer 3

You can set it in constructor as second argument

$date = new DateTime(null, new DateTimeZone('Europe/Rome'));

or later with setTimezone function

$date = new DateTime();
$date->setTimezone(new DateTimeZone('Europe/Rome'));

You can read more about it here http://php.net/manual/en/datetime.settimezone.php

Answer 4

Working with timezones in PHP is pretty easy. Below follows an example:

// Create a new DateTime object
$date = new DateTime('2000-01-01', new DateTimeZone('Pacific/Nauru'));

// Output
echo $date->format('Y-m-d H:i:sP') . "\n";

// Change timezone
$date->setTimezone(new DateTimeZone('Pacific/Chatham'));

// Output again
echo $date->format('Y-m-d H:i:sP') . "\n";
