Zencart 1.5.1 - since the plugin only goes to 1.3.9, I started to manually make the changes. I see in the query factory on 1.5.1, the following:
Code:
        if (getenv('TZ') && !defined('DISABLE_MYSQL_TZ_SET')) @mysql_query("SET time_zone = '" . substr_replace(date("O"),":",-2,0) . "'", $this->link);
But, I don't see where the TZ environment variable is set.

I already set the timezone for PHP 5.2 using the php.ini file.

Is there a recommended way to set the TZ variable through zencart, or should I simply copy over the time_zone_fix.php files from your 1.3.9 plugin?
