Why is my time() off by one hour in php?
提问by zeckdude
I am adding the current date and time to my database using the following code:
我正在使用以下代码将当前日期和时间添加到我的数据库中：
$current_date_time = time();
echo date('n/j/y g:ia',$current_date_time);
It shows up as 11/29/09 12:38am when it should be 11/29/09 11:38am
它显示为 11/29/09 12:38am 而它应该是 11/29/09 11:38am
The time is ahead by one hour. I am in the Pacific time zone and my hosting provider is in Utah, the Mountain Time Zone. Could this be the reason why it is ahead by one hour?
时间提前了一小时。我在太平洋时区，我的托管服务提供商在山地时区犹他州。难道这就是提前一小时的原因吗？
How do I solve this problem? Do I need to remove an hour from the time? If so, how do I do that? Or is there some sort of other way to account for time zone differences so it shows up in Pacific Time Zone time?
我该如何解决这个问题？我需要从时间中删除一个小时吗？如果是这样，我该怎么做？或者是否有某种其他方式来解释时区差异，使其显示在太平洋时区时间？

You solve it by setting the timezone explicitly in your PHP scripts. You can do this with date_default_timezone_set():
您可以通过在 PHP 脚本中显式设置时区来解决它。你可以这样做date_default_timezone_set()：
date_default_timezone_set('America/Los_Angeles');
Here is the list of PHP supported timezones.
这是PHP 支持的时区列表。
You may also want to try a test script calling date_default_timezone_get()to see what it's actually set to to verify that this is in fact the problem.
您可能还想尝试调用测试脚本date_default_timezone_get()以查看它实际设置的内容，以验证这确实是问题所在。
