date():依赖系统的时区设置是不安全的…

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。

<div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">

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');
}

其他回答

这个问题一直困扰我一段时间，因为我试图注入一个“createbucket.php”脚本到作曲家，我一直被告知我的时区是不正确的。

最后，解决这个问题的唯一方法是: $ sudo nano /etc/php.ini

搜索时区

[Date]
; Defines the default timezone used by the date functions
; http://www.php.net/manual/en/datetime.configuration.php#ini.date.timezone
date.timezone = UTC

确保你移除;

最后

$ sudo service httpd restart

然后你就可以出发了:)

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。

您可能需要将时区放在php.ini文件的配置行中。你应该在你的php.ini文件中有一个这样的块:

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = America/New_York

如果没有，添加它(用您的时区替换)。配置完成后，确保重新启动httpd (service httpd restart)。

下面是支持的时区列表。

在我的特殊情况下，我有PHP配置为使用PHP- fpm (FastCGI进程管理器)。当从CLI执行phpinfo()时，我看到了我在php.ini中设置的正确时区，但在浏览器中仍然不正确，导致我的代码失败。我只需要在服务器上重新启动php-fpm服务。

service rh-php56-php-fpm restart

如果您编辑了php.ini，则可能还需要重新启动httpd服务

service httpd restart

如果你不能修改你的php.ini配置，你也可以在你的代码开头使用下面的代码片段:

date_default_timezone_set('Africa/Lagos');//or change to whatever timezone you want

时区列表可以在http://www.php.net/manual/en/timezones.php上找到。
