Laravel 5 配置时区未在 postgres 连接中定义时区答案

【问题标题】：Laravel 5 configure timezone not define the timezone at postgres connectionLaravel 5 配置时区未在 postgres 连接中定义时区

【问题描述】：

我有一个问题：您通常如何在使用 laravel 5 的网站中处理时区？

Postgres 是本地时间，我笔记本的本地时区是巴西利亚。但是应用程序将config/app.php设置为UTC，但config/database.php中的数据库配置没有规范，所以我通过参数找到config("app.timezone")，即UTC。

然后登录后我打印JWT CustomClaims 和巴西利亚的时区来找我。 [0.o]

在 postgres 客户端上运行，我将时区与 UTC 对冲并搜索用户数据，结果正常。所以config/database.php中的这个参数没有解决。

有什么建议吗？

Warning: The system is configured to read the RTC time in the local time zone. This
         mode can not be fully supported. It will create various problems with time
         zone changes and daylight saving time adjustments. The RTC time is never updated,
         it relies on external facilities to maintain it. If at all possible, use
         RTC in UTC by calling 'timedatectl set-local-rtc 0'

【解决方案1】：

也许您必须设置为 PHP 支持的时区。

如果我没有误解，在您的情况下，您正在尝试将时区设置为巴西。

这应该可行：

'timezone' => 'America/Brasilia'

【讨论】：

实际上，我希望应用程序和 postgres 连接使用 UTC 时区，而不是我的巴西利亚当地时间。

【解决方案2】：

我在用户模型中的临时解决方案：

    /**
 * Setting UTC timezone with mutator.
 *
 * @param $value
 * @return string
 */
public function getLastLoggedInAtAttribute($value)
{
    $carbon = Carbon::createFromTimestampUTC(strtotime($value));
    return $carbon->toDateTimeString() . $carbon->getTimezone()->getName();
}

UTC 时区输出：

array:1 [
  "user" => array:4 [
    "id" => 2
    "name" => "Francis Rodrigues"
    "email" => "francis-01@tosystems.net"
    "last_logged_in_at" => "2017-04-07 18:04:31+00:00"
  ]
]
