为什么PHP date()函数会给出不一致的时间？突然出现了2个小时

服务器的时区提前两个小时.

在我的php.ini中,我有date.timezone = America / Los_Angeles

我注意到有时候时间已经过了两个小时.

MySQL字段是类型datetime,而不是null(我只是注意到我没有设置默认值)

我正在使用Codeigniter,如果这很重要的话.

这就是我有时间插入数据库的方法：

$newData [‘time’] = $time = date(“Y-m-d G：i：s”);

之后我插入了一行代码将时间写入错误日志.

log_message(‘错误’,“日期时间是$time”);

为什么时间会这样变化？这部分日志是当地时间下午2:00到2:30.

这一切都来自我网站上的一个页面,耗时29分钟.
