使用DateTime更改時區不會更改它

Question

我試圖根據時區更改時間。我從DB獲取時間和時區，時間看起來像這樣2017-02-23 12:37:19和時區根據this manual page。我不認爲日期時間有錯誤的格式。但問題是，它不會將時間從數據庫時區轉換爲我想要轉換它的時區。

$time = new DateTime($user['date'], new DateTimeZone($user['timezone'])); 
$user['date'] = $time->format('Y-m-d H:i:s'); 

Answer 1

這裏是一個辦法做下去。

$time = new DateTime($user['date'], new DateTimeZone($dbTimeZone)); 
//use $dbTimeZone as the timezone from which you want to convert to your user timezone 

$time->setTimezone(new DateTimeZone($user['timezone'])); 

$user['date'] = $time->format('Y-m-d H:i:s'); 

Answer 2

，你可以將時區設置，試試這個：

$user['timezone'] = 'Europe/Berlin'; 
$user['date'] = '2017-02-24 10:24:08'; 
$dbTimeZone = 'America/Vancouver'; 
$date = new \DateTime($user['date'], new \DateTimeZone($user['timezone'])); 
$date->setTimezone(new \DateTimeZone($dbTimeZone)); 
$sConvertedDate = $date->format('Y-m-d H:i:s'); 
echo $sConvertedDate;
