I wonder if the app isn’t taking into account the local time zone for the device, as sometime during the day (I haven’t figured out exactly when, maybe around noon - and I’m located in Pacific Time) the times for sunrise and sunrise change slightly (by ~1min, which is expected day-to-day).
I think the change might be midnight GMT. Is that possible?
That would be 4pm my time. I’ll check later today.
Yep - right at 4pm, the sunset time changed from 5:17pm to 5:18pm. So the solution is to only update the local sunrise/sunset times at midnight local time (not GMT).
