UTC−06:00 is a time offset that subtracts 6 hours from Coordinated Universal Time (UTC). In North America, it is observed in the Central Time Zone during standard time, and in the Mountain Time Zone during the other 8 months (see Daylight saving time). Several Latin American countries and a few other places use it year round.
