当我请求在服务器上将PHP版本从5.2.17更新到PHP 5.3.21时,我得到了这个错误。

如果你使用Plesk,试试它,首先,打开PHP设置,在页面底部,更改日期。从DEFAULT到UTC的时区。

一个简单的方法,两个时区。

<?php 
$date = new DateTime("2012-07-05 16:43:21", new DateTimeZone('Europe/Paris')); 

date_default_timezone_set('America/New_York'); 

echo date("Y-m-d h:iA", $date->format('U')); 

// 2012-07-05 10:43AM 
?>

在index.php文件中添加以下内容。当我把我的应用程序从XAMPP服务器迁移到Apache 2.2和PHP 5.4时,我第一次遇到了这个问题……

我建议你在index.php文件中,而不是在php.ini文件中。

if( ! ini_get('date.timezone') )
{
    date_default_timezone_set('GMT');
}
<? date_default_timezone_set('Europe/Istanbul'); ?>

对于php(或您的位置)。

我在us-west-2(俄勒冈州)地区托管我的EC2和S3存储桶。当我调用$s3client->listBuckets()来列出我的php中现有的桶时,我得到了异常-“未捕获的异常'异常'与消息'DateTime::__construct():依赖系统的时区设置是不安全的…”。 我做了以下更改,使其工作。分享这些细节,以防有人面临类似的问题,以上任何答案都没有帮助。

Based on documentation @ AWS Configuring Network Time Protocol (NTP), I confirmed ntpd service status is fine by running ntpstat command. If you get error, this link helps you to know what is going wrong. Opened /etc/php.ini file (some may have it in different path based on version of php installed) and found that date.timezone was not set to any value and also it was commented by default. I un-commented by removing ';' before this line and set its value to "UTC" and saved the file. Restarted http and ntp daemons using sudo service httpd restart and sudo service ntpd restart commands.

在此之后,我能够成功地列出桶没有任何例外。希望这能有所帮助。

对于docker用户: 在你的项目中创建一个本地时区。ini文件,在docker-compose.yml中设置配置,

    volumes:
        - "./docker/config/timezone.ini:/usr/local/etc/php/conf.d/timezone.ini"

timezone.ini

    date.timezone=Australia/Sydney
