This doesn't make sense to me. If you're on the extreme western end of a time zone, the clock time of sunset is later compared to points further east in the same time zone. So you're in better shape for post-work sunlight than anyone else in your time zone. The people who have it worst for post-work sunlight are the ones at the extreme eastern end of a time zone.
