This tape-delay is used for a variety of other purposes as well. Then there’s a “western feed” that is tape-delayed for three hours to accommodate the time difference in the Pacific Time Zone. There is an “eastern feed” that is aired at the same time for both the Eastern and Central Time Zones. The same process is true in the case of cable and satellite channels. In most cases, television networks will have two separate feeds that go to their owned-and-operated stations and affiliates. The United States is composed of four separate time zones, which makes timing and scheduling for television broadcasts more complicated. The Effects of Time Zones on American Broadcasting DST schedule after gaining approval from the government in 2010. Some of the border cities adopted the U.S. Mexico has a slight change to this formula and changes their time on the first Sunday in April and the last Sunday in October. On the first Sunday in November, the clocks go from 2:00 to 1:00. In locations where DST is observed, the clocks change from 2:00 local time to 3:00 local time on the second Sunday in March. The exception to this rule is the city of Lloydminster which chose to stay on Mountain Time with DST to stay in sync with Alberta’s time. Most of this example province is geographically located in the Mountain Time Zone, so by moving into the CST Zone, they essentially placed themselves on a permanent Daylight Saving Time. As mentioned earlier, the Canadian province of Saskatchewan does not participate in this practice. This modification is UTC -05:00 instead of the normal six hour offset. A Brief Examination of Central Daylight Timeīetween the months of March and November, a modified time zone is in effect for much of the CST zone called Central Daylight Time. It is denoted with the letter “S” and is combined with military time. This is a military time zone used in aviation and is used at sea between the longitudes of 97.5 degrees West and 82.5 degrees West. This time zone is a DST variation of Mountain Standard Time that falls into the same offset as CST during the summer months. The pacific island of Galapagos near Ecuador falls into this time zone, which is six hours behind UTC. During the summer months the official time is EASST ( Easter Island Summer Time). They are listed below with a short description of each:Įaster Island/Rapa Nui observe this time zone during the winter. There are also several other time zones that fall into the same UTC offset as CST. In Central America, the following countries observe CST all year long: The following Mexican states observe Central Time: They are Baja California Norte, Baja California Sur, Chihuahua, Nayarit, Quintana Roo, Sinaloa, and Sonora. In Mexico, most of the country falls under CST, but six of the states do not. Many of these states are geographically located on the border of two time zones. The Central Time Zone is the most populated in the United States just after the Eastern Time Zone. Texas - all but a few counties including El Paso, Hudspeth, Culberson.North Dakota - North and East locations.Michigan - Several western counties including Dickinson, Gogebic, Iron, and Menominee.Kansas - barring these west counties: Greeley, Hamilton, Sherman, and Wallace use MST/MDT.Indiana - Northwestern counties including Lake, Porter, La Porte, Newton, Jasper, Starke, and counties near Evansville.Florida - Northwestern locations including Calhoun, Escamia, Holmes, Jacson, Okaloosa, Santa Rosa, Walton, Washington, and north gulf counties.Below are locations in the United States that fall into the CST zone: Manitoba is the only Canadian province that observes Central Time in its entirety. Saskatchewan - Only in Creighton and Denare Beach.The following communities do not observe DST: Atikokan, New Osnaburgh, Pickle Lake Ontario - areas west of 90 West, the eastern side is on EST/EDT.During Daylight Saving Time, participating areas move from 6 hours behind UTC to five hours for the portion of the summer.īelow are the areas in Canada that fall into this time zone: Parts of the United States, Canada, Mexico, Central America, the Caribbean Islands, and a portion of the Eastern Pacific Ocean utilize CST.
