![]() So I downloaded a bunch (trying to look for ones with fairly recent dates), and ended up just importing them into Google Earth Pro to plot them on the globe. Once you do that search, you’ll find there area a TON of data sets. Since I know that Google Earth and Google Maps accept KML (as well as KMZ or SHP files), I did a search for: (In particular: ne_10m_time_zones.shp, from the 1:10m cultural vectors.) He also said that NaturalEarth is an amazing collection of map data–he’s right.īut that motivated me to look around a bit for other time zone data. When I asked him, Brandon kindly replied that he got the data from and created it from that. I ran across this map before I wrote this Challenge and liked it so much that it led me to re-cast his map as the Challenge. (He has a great blog–highly recommended if you’re into maps.) I really like the map that CartographerWithoutBorders author Brandon Rishel made. Can you create your own time zone map by finding data that gives the actual boundary lines for each zone? (If you do make your own map, please share the URL for your creation! We’d all love to see it.) (Which also, by the way, gives the Newfoundland TV station the ability to run “Television World Premiere” as a bumper when it shows some new TV show…)Ģ. It fits better with the local time, and the locals like it. In 1963, the Newfoundland government attempted to bring the province into conformity with the other Atlantic provinces, but withdrew in the face of stiff public opposition.” John’s, the province’s capital and largest city. While the entire province lies west of the standard meridian for a half-hour time zone, 52.5 degrees west longitude, this is also the near exact meridian of St. ![]() Since it was separate from Canada, it had the right to adopt its own time zone. The island of Newfoundland lies squarely in the eastern half of the Atlantic Time Zone, exactly three and a half hours from Greenwich. The NTZ entry on Wikipedia tells us that “This time zone exists because of the location of the island and the fact that it was a separate dominion when the time zones were established. ![]() (Unlike, say, the Pacific Daylight Time Zone, where I live, which is GMT – 7 hours or the Atlantic Standard Time Zone (which PEI follows defined as GMT – 3). Yes, it’s NOT an integer number of hours different than GMT. It’s pretty straightforward to find out what time it is in Newfoundland–the query:Īnd learn that the time in Newfoundland is GMT-2:30. What time is it in Newfoundland (Canada)? And why is it different than the time in Prince Edward island (which is due south of Newfoundland)? ![]() OversightĭOT is responsible for fostering and promoting uniform time observance.Let’s look at our questions one at a time.ġ. The time zones established by the Standard Time Act, as amended by the Uniform Time Act, are Atlantic, eastern, central, mountain, Pacific, Alaska, Hawaii–Aleutian, Samoa, and Chamorro. §§ 260-64) establishes a system of uniform Daylight Saving Time throughout the Nation and its possessions, and provides that either Congress or the Secretary of Transportation can change a time-zone boundary. Today, the Uniform Time Act of 1966 (15 U.S.C. This responsibility was transferred from the Interstate Commerce Commission to DOT when Congress created DOT in 1966. Local decisions on which time zone to adopt were usually influenced by the time used by the railroads.įederal oversight of time zones began in 1918 with the enactment of the Standard Time Act, which vested the Interstate Commerce Commission with the responsibility for establishing boundaries between the standard time zones in the continental United States. States and municipalities then adopted one of the four zones, which were the eastern, central, mountain, and Pacific Time zones. and Canadian railroads adopted a four-zone system to govern their operations and reduce the confusion resulting from some 100 conflicting locally established “sun times” observed in terminals across the country. States do not have the authority to choose to be on permanent Daylight Saving Time. Under the Uniform Time Act, States may choose to exempt themselves from observing Daylight Saving Time by State law. If a State chooses to observe Daylight Saving Time, it must begin and end on federally mandated dates. Nor does DOT have any role to play in a State's determination whether to observe Daylight Saving Time. DOT regulations at 49 CFR part 71 contain the official listing of the Nation's time zones.ĭOT also oversees the Nation's uniform observance of Daylight Saving Time however, DOT does not have the power to repeal or change Daylight Saving Time. The oversight of time zones was assigned to DOT because time standards are important for many modes of transportation. Department of Transportation (DOT) oversees the Nation's time zones.
