U.S. time zones
Standard time and time zones were first introduced on US railroads in 1883. In 1918, the US Congress adopted the “Standard Time Act”, thereby legislating the system of dividing the country into time zones that had already actually developed by that time.
At present, the US Department of Transportation is responsible for determining the boundaries of time zones and other issues related to standard time in the US government. Federal legislation also determines the procedure for switching to daylight saving time.
The continental United States is divided into four time zones:
- Eastern time zone (designation ET)
- Eastern Standard Time UTC-05 EST
- Eastern Daylight Time UTC-04 EDT
- Central time zone (designation CT)
- Central Standard Time, UTC-06, CST
- Central Daylight Time, UTC-05, CDT
- Mountain time zone (UTC-07, designation MT)
- Mountain Standard Time, UTC-07, MST
- Mountain Daylight Saving Time, UTC-06, MDT
- Pacific Time Zone (UTC-08, designation PT)
- Pacific Standard Time, UTC-08, PST
- Pacific Daylight Time UTC-07 PDT
