TIME ZONE STUDIES
Bill Rankin, 2002
The inscription of politics (and the nation-state) not just in space, but in time as well. Countries are differentiated by as little as 15 minutes from their neighbors (in the case of Nepal), or consolidated into huge zones where some citizens wake up hours before dawn (in the case of China).
Notice also how time zones tend to be drawn slightly to the west of "natural" solar time zones, shifting daylight later to align more closely with modern business schedules. But (at least in the US) outdoor workers like farmers and construction laborers keep their schedules in line with the sun, making them abnormally early risers.
