I live in Europe, Sweden. Back in the day, before we edited the DST, eggs started to pop up at 7:00 AM earliest. And we had active raids as late as 21:45. That was the raid window basically. Then we turn clock back one hour, alright. A week later, USA also turns their clock back. The result? We are getting eggs at 5:00 AM. Niantic, fix. Nobody raids at 5:00 AM.
