想试试cakephp,将其解压到apache的htdocs目录后,访问出现strtotime调用问题、时区设置问题

lampkid 2011-06-28 03:14:49
下面是访问cakephp目录下的index.php浏览器给出的提示

只不过又出现了新的错误:

上面那个问题终于解决了,不过又出现了新的问题,待我先记录下来:

这是 php 5.3 才有的错误
你需要设置时区,
可以在 php.ini 中设置 date.timezone 的值
也可以在程序中用 date_default_timezone_set() 函数设置
参数为 PRC

按提示说,是时区设置的问题,但是strtotime和时区设置有什么关系,这个函数至于时间戳的起始时间有关,即1970年1月1日0点整。
提示说依照系统时区设置不安全,让我使用date.timezone 或date_default_timezone_set() ,怎么搞?初次接触,就遇到这样一个问题。求各位帮忙、、
