Found the issue,
We calculate sunrise and sunset at 12:01am everyday and we correctly adjust for daylight savings transitions at that time.
However if you reboot your hub or change the, lat/long, we recalculate the sunset and sunrise times. On the day of transition only after the transition has occurred we end up miscalculating the times.
You should reset your timezone back to the correct one and it should calculate the right sunrise/sunset time tomorrow. There will be a fix for this in the next release.
