I think it was during the 1879. Hope it helps!:D If not search it on Wikipedia.
Time zones were officially established in the US on November 18, 1883 by the railroads in order to standardize schedules. This was known as the Standard Time Act, which divided the US into four time zones: Eastern, Central, Mountain, and Pacific.
There are 4 time zones in the continental US. Alaska and Hawaii each have their own time zone.
Time zones were first introduced in the United States in 1883 by the American railroad industry to standardize schedules and improve efficiency. This system was implemented after the Interstate Commerce Commission established 4 standard time zones for the continental US.
In the US there are six time zones, they have names they are called in the US and also have Greenwich Mean Time (GMT) Zone names: * US Eastern Standard Time = GMT - 5 * US Central Standard Time = GMT - 6 * US Mountain Standard Time = GMT -7 * US Pacific Standard Time = GMT - 8 * US Alaska Standard Time = GMT - 9 * US Hawaii-Aleutian Standard Time = GMT -10 In Summer most states in the six US time zones observe Daylight Savings Time and then the name of the zone would be, for example, US Eastern Daylight Time Zone.
Canada has six time zones, while the contiguous United States has four time zones (Eastern, Central, Mountain, and Pacific).

The US does have six time zones. Starting from the West they are Hawaii-Aleutian, Alaska, Pacific, Mountain, Central and Eastern Zones.
Canada uses 6 primary time zones, Unlike the United States that uses 9 primary time zones. ALL time zones go from east to west. CANADA'S TIME ZONES ARE: * Newfoundland * Atlantic * Eastern * Central * Mountain * Pacific UNITED STATES' TIME ZONES ARE: * Atlantic * Eastern * Central * Mountain * Pacific * Alaskan * Hawaii-Aleutian * Samoa * Chamorro The US and Canada have 5 time zones in common. Since there are more then one time zones within Canada and the US, we can't just say "The difference is ______" and give you a straight answer. Canada and the US have different time zones and they were listed. EDIT: Depending on whatever time zone or country (US or CANADA) you are in, the difference should be asked between the two time zones. EXAMPLE: "What is the time difference between Eastern time to Hawaii-Aleutian time?"

The Continental US has 4 time zones. From east to west they are Eastern, Central, Mountain, and Pacific time zones.
Alaska
November 18, 1883
There is different parts that have time zones
Sir Sandford Fleming, a Canadian engineer and inventor, is credited with proposing the concept of worldwide standard time and time zones in the 1870s. The time zones for the United States were formally established through the railroads' adoption of standard time in 1883, based on Fleming's principles.
