So your php.ini has no time limit (0) and your .htaccess file (or some
script settings before you do phpinfo()) is changing it to 1800, which is
30 minutes.

Note that time PHP spends waiting for stream input, system calls, database
queries etc does *NOT* count.
So it's quite possible that:
You are not executing phpinfo() under the same environment as your real
script.
Your code does a ton of db queries or system calls or waiting for streams,
and PHP only "counts" 30 seconds of the 6 to 10 minutes being spent.
The amount of time PHP spends waiting for system calls, streams, and db
queries is highly variable, and accounts for the 6 to 10 minutes range --
as well as the fact that PHP dies out at seemingly random different places
in your source.

At the *TOP* of your real script, use http://php.net/error_log to log
ini_get('max_execution_time') and see what you've got.
Or try to run your phpinfo() test in exactly the same manner as your cron
job.
