In Time (2011)
The stated coordinates place the location as Vernon, CA. If one looks at the map in the movie, this corresponds to Time Zone 12 (i.e. Dayton).
If one compares this map to a real-world map, one will also see that the shape of the depicted map corresponds nearly precisely to the real-world California coastline south and west of Los Angeles. Thus, Time Zone 4, that of New Greenwich, would be the Hollywood-Beverly Hills-Santa Monica corridor.
Note also that later in the film, Philippe Weis appears to only be in charge of Global Time Zone 16 out of 24 Global Time Zones.
