is universal time(UT) == Greenwich Mean Time (GMT)?

They are one in the same. Both are based on the local time in Greenwich, England. This is the standard by which the scientific community bases their observations for things such as weather events or astronomical events, ect.

I have debated this once with another knowledgable person. We came to a conclusion that any calculation/prediction is applicable at only time. This time has different representations in different time zones.\nTo explain a little further. These effects are caused because of a planetary/celestial body movement. That happens at a particular instant (assuming a global time - ofcourse this is a violation of laws of relativity). So if the effects are predicted for 12 noon PST then it is valid in India at 12:30AM the following day and so on...

The United Kingdom (AKA Great Britain, England etc.) is at exactly GMT 0. In other words, as Arizona is at GMT-7 you simply add on the hours you need. (However if it is summertime you add on 8 hours) \nSo 10:00 becomes 17:00 (05:00 PM)

Coordinated Universal Time.  The UTC acronym was a compromise between English & French.\n\nUTC was formerly known as GMT (Greenwich Mean Time), and is called Zulu by the military and for aircraft operations (at least in the US, not sure about elsewhere).

if you usually take it at say 5 pm you just see the time difference and that is in the uk say 1 pm. so you take it at 5 pm your time which might be as i said 1 pm uk time.

I don't know what CMT is, but it's at 19:00 UTC.\n\nreply to Juanes34.. if by Eastern time you mean e.g New York time, then 3pm Eastern is not 8pm GMT - the UK has daylight savings time as well, indeed was the one of the first countries to introduce it, and is currently 1 hour ahead of GMT

Its not that the times are different in different countries, it has to do with time zones. There are 16 (I think) different time zones around the world, so that no matter where you are in the world, the time will be about the same to where the sun is.\nTo learn more try the link

no\ntime is a man made thing, to quantify a distance we travel in the grand scheme of things\nexample: we use 24 hours for a day. had i been involved in the creation of this, we would have 273 gronks in one turewion, which would be equal to our current day. a day is logically based on one rotation of the earth, and a year a spin around the sun, so a turewion would equal a day, a fioreter would equal a year, but a month would not exist, nor a week\n\nlampoilman - thats pretty deep, got any 'cid left

Times written in military time (24 hour format) are four digits, such as, 1830Z (6:30 pm) with the Zulu suffix. Note that the phonetic alphabet is used for the letter Z (Zulu). This time is usually referred to as Zulu Time because of the letter assigned to this time zone. \n\nIts official name is Coordinated Universal Time or UTC. This time zone had previously been called Greenwich Mean Time (GMT) but was replaced with UTC in 1972 as the official world time standard changed. While GMT is based on Earth's rotation and celestial measurements, UTC is a based on cesium-beam atomic clocks. The two clocks are rarely more than a second apart as leap seconds are applied to UTC.\n\nSo, Zulu Time is taken from Greenwich in London. On the West Coast of the US, we are 8 hours behind that time

The USA has several time zones: Eastern (GMT-5), Central (GMT-6), Mountain (GMT-7) and Pacific (GMT-8).  See the site below to learn more.

Australia is GMT + 10\nItaly is GMT + 1\n\nTherefore, the difference between them is 9 hours. \nItaly is 9 hours behind Australia.

By convention, most who visit the North Pole use Greenwich Mean Time (GMT), which is the time registered at the observatory in Greenwich, England

World standard time, based on Greenwich Mean Time, recognizes local AM and PM notations. 12:00 noon is PM, 12:00 midnight is AM. \n\nIM is not a recognized standard of time, although the locals in Meridia may well use the term loosly if they're confused about what time it is.

Start by getting the 12:00pm GMT out of the question... if your longitude is 6h17m32.143sW of the Prime Meridian, then your time zone is an even -7 hours offset from GMT.\n\nThe more precise question would be, "At my location, solar time at solar noon GMT is 6:17:32.143am. My latitude is 44°44'45.694"N. Where am I?"\n\nTo convert the time reference to longitude, consider that the International Date Line (180°E & 180°W) is 12h0m0sW of the Prime Meridian. 6h0m0sW would be an even 90°W. \n\n6:17am yields a differential of 5h42m27.857s. Convert that to seconds (5*60*60 + 42*60 + 27.857), divide by 43,200 (12h*60m*60s) and multiply that by 180° to get your numeric longitude, then multiply the decimal portion out to determine your minutes and seconds of longitude.
