USA time-zones?

Question

Hiya! Can someone tell me where the Pacific Time Zone in the USA ends and then becomes Eastern Time? Answers as states or cities will be appreciated.

Answer 1

L.A = Pacific
Denver - Mountain
Chicago =Central
N.Y. = Eastern

Answer 2

The Pacific and Eastern Time zones do not touch; eastern time is three hours ahead of Pacific time, so when it's midnight in the Eastern time zone, it's 9:00 p.m. in the Pacific time zone. Going from east to west, the time zones in the continental United States are Eastern (GMT -5:00); Central (GMT -6:00), Mountain (GMT -7:00) and Pacific (GMT -8:00). Example cities for the various zones are New York City for Eastern time; Dallas for Central time; Denver for Mountain time, and Seattle for Pacific time.

Answer 3

The pacific time zone doesn't touch the eastern time zone. You have Pacific, Mountain, Central and Eastern (from West to East).

Answer 4

A time zone is a region of the Earth that has adopted the same standard time, usually referred to as the local time. Most adjacent time zones are exactly one hour apart, and by convention compute their local time as an offset from Greenwich Mean Time (see also UTC).

Standard time zones can be defined by geometrically subdividing the Earth's spheroid into 24 lunes (wedge-shaped sections), bordered by meridians each 15° of longitude apart. The local time in neighbouring zones is then exactly one hour different. However, political and geographical practicalities can result in irregularly-shaped zones that follow political boundaries or that change their time seasonally (as with daylight saving time), as well as being subject to occasional redefinition as political conditions change.

There are variations of the definitions of time zone which generally fall into two meanings: a time zone can represent a region where the local time is some fixed offset from a global reference (usually UTC), or a time zone can represent a region throughout which the local time is always consistent even though the offset may fluctuate seasonally.

Before the adoption of time zones, people used local solar time (originally apparent solar time, as with a sundial; and, later, mean solar time). Mean solar time is the average over a year of apparent solar time. Its difference from apparent solar time is the equation of time.

This became increasingly awkward as railways and telecommunications improved, because clocks differed between places by an amount corresponding to the difference in their geographical longitude, which was usually not a convenient number. This problem could be solved by synchronizing the clocks in all localities, but then in many places the local time would differ markedly from the solar time to which people are accustomed. Time zones are thus a compromise, relaxing the complex geographic dependence while still allowing local time to approximate the mean solar time. There has been a general trend to push the boundaries of time zones farther west of their designated meridians in order to create a permanent daylight saving time effect. The increase in worldwide communication has further increased the need for interacting parties to communicate mutually comprehensible time references to one another.

Answer 5

Hehe - USA has 4 time zones. Pacific, Mountain, Central and Eastern.

The Pacific/Mountain time boundary from north to south runs between Idaho/Montana, then to Oregon/Idaho, Utah/Nevada, and California/Arizona.

You don't really want to know the rest - do you?

Answer 6

If you double click on the clock on the bottom right of your computer screen this brings up a panel called Date & Time Properties, then click on Time Zone this will show all the worlds times when you click on the time panel gust run down them and it will give you the time zones across the United States or any given time in the world.

Answer 7

Atlantic time (Puerto Rico & the yankee Virgin Islands) jap time (the jap continental US) significant time (the significant US) Mountain time (the Rocky Mountain selection and the states in that section. Arizona does not have daylight hours reductions so part of the 300 and sixty 5 days they're in Mountain time and something of the 300 and sixty 5 days they're in Pacific time. different than for the Navajo reservation. they have daylight hours reductions time and are constantly in Mountain time) Pacific time (the western seaboard) Alaskan time (Alaska) Hawaii-Aleutian time (the Hawaiian Islands) Samoa time (US Pacific territories) Chicago is in significant time. (UTC is the time the militia & the government makes use of to coincide w/ Greenwich propose time)

Answer 9

They don't touch...AT ALL.....umm....go to google and U.S time zones.....Maybe look at a map too.
