date_default_timezone_set showing incorrect time
提问by Yeti
I uploaded the following to a server in the US:
我将以下内容上传到美国的服务器：
date_default_timezone_set('Asia/Calcutta');
echo date("Y-m-d H:i:s"); // time in India
The time displayed is 15 minutes prior to that of the actual time in India.
显示时间比印度实际时间早15分钟。
What am I doing wrong here? What code will alwaysshow the time in India accurate to the second?
我在这里做错了什么？什么代码将始终显示印度的时间精确到秒？

It is all relative to the time set on the server. Check the correct time is actually set on the server - maybe it's 15minutes out for the timezone it is set in?
这一切都与服务器上设置的时间有关。检查服务器上实际设置的正确时间 - 也许它设置的时区是 15 分钟？

Its just spelling mistake it should be like this
只是拼写错误应该是这样的
date_default_timezone_set('Asia/Kolkata');
回答by Kalaivani M
date_default_timezone_set('Asia/Kolkata');
$timestamp = date("Y-m-d H:i:s");

I had the same problem when testing out the code on my local xampp server. Here is what I did, changed the timezone default setting to in the php.ini file.
我在本地 xampp 服务器上测试代码时遇到了同样的问题。这是我所做的，将时区默认设置更改为 php.ini 文件中。
date_default_timezone_set('Asia/Kolkata');
date_default_timezone_set('亚洲/加尔各答');
yes agree, not entirely necessary
是的 同意，并非完全必要
Then, declared date_default_timezone_set('Asia/Kolkata') on my config.php file, entirely necessary to set the timezone to your local timezone.
然后，在我的 config.php 文件中声明 date_default_timezone_set('Asia/Kolkata') ，这完全有必要将时区设置为您的本地时区。
Even after this my time and date were 12 hours apart and here is the catch, on checking my windows operating system settings I found that my system time was wrongly set. On correcting my (windows) operating system time zone everything worked perfectly.
即使在此之后，我的时间和日期相隔 12 小时，这就是问题所在，在检查我的 Windows 操作系统设置时，我发现我的系统时间设置错误。在更正我的（Windows）操作系统时区时，一切正常。

$ab = date_default_timezone_get();
date_default_timezone_set($ab);
echo date('dd-mm-Y H:i:s');
