UTC−06:00

From HandWiki

UTC−06:00 is an identifier for a time offset from UTC of −06:00. In North America, it is observed in the Central Time Zone (Spanish: Zona Centro) during standard time and in the Mountain Time Zone during the other eight months (see daylight saving time). Several Latin American countries and a few other places use it year-round.
