SUMMARY

I absolutely love the Day/Night time switch and I've been waiting for it for a very long time, but after using it for a while, the fact that switch occurs at the end of the sunrise/sunset puts it in a wrong time. At least here in southern Germany at "Sunset starts at <time>" it's already dark. There is already another request for the offset here https://bugs.kde.org/show_bug.cgi?id=515533, which is also valid, but I still think that even in a current form the switch should occur on the start of the event and not at the end, because there is 35-40 minute difference there for me. Maybe give it a toggle (Start, End, middle point(?))

STEPS TO REPRODUCE
1. Set Day/Night cycle based on device location
2. Wait until official sunset time

OBSERVED RESULT

Nothing happens at the official sunset time, instead it happen at "Sunset ends at <time>"

EXPECTED RESULT

I strongly feels it should happen at the beginning of the event, unless it's different in other parts of the world, then it should be configurable.
