我仍在研究为什么MAMP覆盖php.ini date.timezone设置的原因和方式，但是，我在Symfony php中找到了快速解决方案文件，至少在目前为止，该文件已解决了该问题.

I am still working on figuring out why and how MAMP overrides the php.ini date.timezone settings, however, I have found the quick fix solution within Symfony php files, which solved the problem, at least for now.

我添加了以下代码:

date_default_timezone_set ('America/New_York');

-在Symfony的config.php和app_dev.php文件的顶部，紧接在脚本顶部的php标签之后.这消除了警告消息，并使Symfony在MAMP上工作.

-- at the top of Symfony's config.php and app_dev.php files, immediately after the opening php tag, at the very top of the script. This removed the warning message and got Symfony working on MAMP.

我预见到必须不断将相同的代码添加到Symfony中的其他php文件中，因为我一直对此进行黑客攻击，这应该不是问题.或者，我可能会弄清楚如何覆盖MAMP的覆盖.

I foresee having to add the same code to some other php files inside Symfony as I keep hacking at it, which shouldn't be a problem. Or I may figure out how to override MAMP's overriding.

仍然，这是一个可行的解决方案.

Still, this is a workable solution.
