Time zones were created by the US railroads as a means of making their published service schedules easier to create and to use.
There are 4 time zones in the continental US. Alaska and Hawaii each have their own time zone.
The division of the US into standard time zones was first done by the American Railway Association in 1883. This system was implemented to create uniformity in timekeeping for the growing railway network across the country.
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.
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).

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?"
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.
