PHP wrong date/time
提问by relic
PHP date()& time()return incorrect time:
PHP date()&time()返回错误的时间：
When date.timezone = "Europe/Riga"the time returned by date()was 03-12-2011 08:57:12, but system time was 03-12-2011 01:57:12(timezone Europe/Riga - correct time at that moment).
When I changed timezone to "Europe/London", the time changed to 03-12-2011 06:57:12( actual time 02-12-2011 23:57:12)
当date.timezone = "Europe/Riga"返回的时间date()是03-12-2011 08:57:12，但系统时间是03-12-2011 01:57:12（时区欧洲/里加 - 当时的正确时间）。当我将时区更改为“欧洲/伦敦”时，时间更改为03-12-2011 06:57:12（实际时间02-12-2011 23:57:12）
Time returned by date/ hwclock --showwas correct (03-12-2011 01:57:12with system timezone set as Riga)
date/返回的时间hwclock --show是正确的（03-12-2011 01:57:12系统时区设置为里加）
OS: Debian 6.0
操作系统：Debian 6.0
I have checked most of the questions regarding similar issues on SO/Google, but they all seem to have wrong timezone specified.
我已经在 SO/Google 上检查了大多数关于类似问题的问题，但它们似乎都指定了错误的时区。
As far as I can tell there is problem between php -> os. Of course, because the incorrect time offset is always constant I could subtract difference, but it is not a proper solution.
据我所知，php -> os. 之间存在问题。当然，由于不正确的时间偏移始终是恒定的，我可以减去差异，但这不是一个正确的解决方案。
Any ideas will be greatly appreciated.
任何想法将不胜感激。

The problem looks similar to what I have seen on one of my servers. Looks to like bug in php 5.3.2-1. Try to run the php script in the bug report and post your results.
该问题看起来与我在其中一台服务器上看到的类似。看起来像php 5.3.2-1 中的错误。尝试运行错误报告中的 php 脚本并发布您的结果。

Reading PHP manual seems that behaviour of date.timezoneis affected by settings in php.ini. There is another way to set the default timezone in all date/time function and it's the date_default_timezone_set. Try to set it with:
阅读 PHP 手册似乎date.timezone 的行为受 php.ini 中的设置影响。还有另一种方法可以在所有日期/时间函数中设置默认时区，它是date_default_timezone_set。尝试设置它：
date_default_timezone_set('Europe/Riga');
instead of your date.timezonecode.
而不是您的date.timezone代码。

The timezone of the system could be wrong. This results in a shift in a time given by the PHP date() function, althought both php date.timezone (in php.ini) and system time of the server are correct.
系统的时区可能是错误的。这会导致 PHP date() 函数给出的时间发生变化，尽管 php date.timezone（在 php.ini 中）和服务器的系统时间都是正确的。

You have to set date.timezone in php.ini and restart your server http://php.net/manual/en/timezones.php
您必须在 php.ini 中设置 date.timezone 并重新启动服务器 http://php.net/manual/en/timezones.php

PHP time is based on epoch time scale which uses GMT and later UTC. Most people now refer to it as unix time. Because PHP uses unix time, timezones are not used. I believe subtracting the timezone hours in seconds is the correct method to adjust for the differences.
PHP 时间基于使用 GMT 和后来的 UTC 的纪元时间刻度。大多数人现在将其称为 unix 时间。因为 PHP 使用 unix 时间，所以不使用时区。我相信以秒为单位减去时区小时数是调整差异的正确方法。
