Railroads operated with 100 different time zones before America moved to four, which was consistent with Britain’s push for a global time standard. This made operations very difficult for the telegraph and burgeoning railroad industry. That led to more than 300 different American time zones. Before that, each city had its own time standard based on its calculation of apparent solar time (when the sun is directly over-head at noon) using sundials. According to Time and Date, a Norwegian newsletter dedicated to time zone information, America started using four time zones in 1883. How we measure time has always evolved with the needs of commerce.

The purpose of uniform time measures is coordination. Anyone who lives on one coast and does business with the other can imagine the uncountable benefits of living in a two-time-zone nation (excluding Alaska and Hawaii). The east and west coasts will only be one hour apart. This will result in just two time zones for the continental United States. After that we won’t change our clocks again-no more daylight saving.

This year, Americans on Eastern Standard Time should set their clocks back one hour (like normal), Americans on Central and Rocky Mountain time do nothing, and Americans on Pacific time should set their clocks forward one hour. I propose we not only end Daylight Saving, but also take it one step further. Being out of sync with European time changes was at one point projected to cost the airline industry $147 million a year in travel disruptions. There’s evidence that regularly changing sleep cycles, associated with daylight saving, lowers productivity and increases heart attacks. Frequent and uncoordinated time changes cause confusion, undermining economic efficiency.

The actual energy savings are minimal, if they exist at all. It would seem to be more efficient to do away with the practice altogether. It also creates confusion because countries that observe daylight saving change their clocks on different days. The fall time-change feels particularly hard because people lose another hour of evening daylight, right around the time the days are growing shorter anyway. It’s a controversial practice that became popular in the 1970s with the intent of conserving energy. UTC offsets in diagonally striped areas are not whole hours.Daylight Saving Time has ended once again, setting off an annual ritual in which Americans (except for those who live in Arizona or Hawaii) and residents of 78 other countries-including Canada (but not Saskatchewan), most of Europe, Australia and New Zealand-turn their clocks back one hour. Find the current time offset – displayed in whole hours only – from Coordinated Universal Time (UTC) at the bottom of the map.(Doesn't work in older versions of IE – IE8 and below.) Hover your mouse over the map to highlight time zones.Click on any red dot and go to that city's page with time, weather, sunrise/set, moon phases and lots more.“DST” is displayed if there is Daylight Saving Time at the moment. Hover your mouse over any of the red dots to see the name of the city and country and current local time.To remove the pins permanently (undo not possible), simply click here or on the Time Zone Map link in the menu above.If you place more than one pin, an extra line of information is added underneath the map with links to those cities' pages. Search for any city in the search field above and place a black "pin" by that city on the map.Please note that the Time Zone Map is not a political map but a time zone map showing the time zone boundaries.
