The eastern part of a time zone has earlier sunrise/sunset than the western part of that same time zone. A little past Detroit would have Vancouver times.
Maybe winter, but if you check longest Sumner day as a common point, Vancouver has earlier sunrise by 25-30 minutes, and earlier twilight by 40…compared to detroit. I have lived in both areas .
It is also not just about the time zone positions laterally because the sun shadow is at an angle compared to longitude due to precession angle I assume. If you lookup sunshadow animations you will see what I mean.
