Correct timezone, but with DST still 1 hour wrong


I’m receiving items from a RSS feed. They use for time declaration GMT like:

<pubDate>Fri, 10 Feb 2017 14:56:00 GMT</pubDate>

The right time should be: 15:56 (+1 hour due Daylight Saving Time). I live in Holland, Amsterdam.

So that’s why I convert it like: date(“d-m-Y H:i:s”,strtotime($item->pubDate))

Of course I have to put the right timezone in my config and I did: ‘timeZone’ => ‘Europe/Amsterdam’,

But the result is still 14:56.

What am I overlooking? Is there another setting I should be aware of?
