I just noticed that when I have am using your package to benchmark, my timezone is overwritten

By default I have it set to Singapore

in my config/app.php

I have

'timezone' => 'Asia/Singapore',

I was running benchmarking on aggregate queries that use the dates and I was noticing that my graphs were off and different from my production data even though I am using the same database data

I think it's because of this line:

    private function setDefaultTimeZone()
    {
        // Check date function
        if( ! ini_get('date.timezone'))
            date_default_timezone_set('UTC');
    }

In your ConfigHandler.php

Is this really necessary ? Shouldn't your benchmarking work regardless of what timezone is set?
