Mexico City's clock differs from border schedules
Mexico City currently stays on UTC−6 throughout the year. Seasonal clock changes still apply in specified northern-border areas of Mexico, but not in the capital. A generic Mexico or Central Time label is therefore not enough to identify the correct schedule.
Chicago shares Mexico City's standard offset but moves to UTC−5 during daylight saving. If a device unexpectedly shifts Mexico City by an hour, its time-zone data may be outdated. Update the device and check the official Mexican time service before relying on it for a departure or deadline.
