***is universal time(UT) == Greenwich Mean Time (GMT)?***\n-\nThey say (at:http://scienceworld.wolfram.com/astronomy/UniversalTime.html) that:\nUniversal time (UT) is simply the number of hours, minutes, and seconds which have elapsed since midnight (when the Sun is at a longitude of 180°) in the Greenwich time zone.\n\n--\nplease give the reference URLs or other clarifications/proofs for your answer. I will really appreciate this courtesy of yours.\n\nThank you very much indeed.\n\nSalman Ahmad\nLHR, PK

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.

Judge for yourself based on this: Time is a MAN MADE construction. That is, it is not a natural element in life. For those of you who would argue, please answer how it can be set back and set forward (daylight's saving time). If it were natural you wouldn't be able to limit it to the watches you wear or the clocks on the wall. It would be beyond any human control and it would be very hard for anyone to grasp the concept and explain it. As it is, we CAN explain it and grasp it, therefore, it is not natural.\n\nSo my answer is no.\n\n\n\n\n\n\n\n\n\n\n.

Is that 3 a.m. GMT? E.S.T? Swatch time? Spirits often get confused by time zones. I was once visited by a sprit who thought it was 3 a.m. but it turned out to be jetlag.\n\nCome on... don't believe that religious hocus pocus. Probably your mind has set up some kind of internal "alarm clock" for any number of reasons. It'll go away eventually - spirits or no spirits.

Since there are 27 integer time zones (from GMT - 12 hours to GMT + 14 hours), there's no way the whole world can have the same date at the same time, because there will always be points that are more than 24 hours apart, and those points (at least) will be in different days.

Actually, me too!  I look at the clock all the time-- morning and night, and it's 9:11!  I thought, it's amazing.  I went through a period of about 6 months whenever I looked at the clock, it was specifically that time.  I thought maybe it was just in sync with my biological clock, but I couldn't shake the significance of those numbers.  I'm not sure what it all means-- but I do not believe in coincidences.  It's something worth looking into, definitely.  I'll be interested to find out your results.

ya, that one has the same dimension as that of time.see how that eqn is derived.you find distance covered by 'n' seconds then distance covered by (n-1) seconds.subtract.and you get the eqn.... but see wat is the difference b/w the time n and n-1. it is one second..this is the one that appeared in the eqn and confused you.is it clear?

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.

If its 15:34 in brazil the whole worlds time should be ending with rather :34 or :04.  It's all based on Greenwich mean time (GMT) Which is the time in a place in england.  All time zones are based around this time.  For example central america is 5 hours behind GMT so if it is 5:34 in england it is 12:34am or 0:34 in Central America.  Most of the time zones are in one hour increments however there are some that are a half hour difference.\nBTW there is no such thing as 7:84 or 13:64 in any country.

I've never found that, but I have found that at Daylight Savings Time, it will change.  It doesn't even sound plausible, but it always works like that. I'm really not sure why, but my mom and best friend have the same problem.  Who knows.

Ask around if any of your friends have a GPS system.  There is your example of a daily-life example of the theory of relativity.  The Global Positioning System would not be able to give you very accurate locations if it did not take the corrections to time and distance from both special, and general reletivity into account.  I am pretty sure that it is the first piece of public consumer-grade equiptment that relies on our understanding of General Relativity.

>There are 24 longitudinal divisions of Earth's surface in which a standard time is kept, the primary division being that bisected by the Greenwich meridian. Each zone is 15° of longitude in width, with local variations, and observes a clock time one hour earlier than the zone immediately to the east.Under this scheme, local time is always close to mean solar time, while comparing the time in different places is a simple matter of adding or subtracting whole hours. However, the one hour separation is not universal and,the shapes of time zones can be quite irregular because they usually,but not always,follow the boundaries of states,countries or other administrative areas.Some states do have more than one time zone.

I don't know, but I am now very curious as to where this question comes from. I mean, why those particular angles? And what angles are they anyway? Right ascension expressed in degrees instead of hours? Celestial latitude? And why the extreme precision, specified to within 1/10,000 of an arc second?\n\nAnyway, here is a good web site for showing the sky at any time you like. Now all you have to do is try different times until that alignment appears. What a chore!

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.

Here's a cool way to get a good estimate:\n\nFind the time difference between each city and multiply by 1,041 and you will have a close guestimate.\n\nReason? The Earth is approx 25,000 miles at the equater but divided into 24 time zones.  That makes each time zone about 1,041 miles apart.

Latitude doesn't affect time at all. For Longitude, since 360 degrees encompasses the entire earth's surface, and since the earth rotates once in 24 hours, the time between two points one degree apart in longitude is 24/360 or 4/60 or 1/15 of an hour, which is 4 minutes. (you can break this down as far as you want, using smaller and smaller longitudinal differences). As an offshoot of this, there are 15 degrees in an arc of the earth representing  one time zone. By the way, there is no "local time" at either the North or South Pole, but that's a story for another time.

OK, it depends on where you are at in the world. \nIf you are in New York city, subtract 5 hours from the GMT time to get local time. Chicago 6, Denver 7, Los Angeles 8; you get the picture. Of course, that changes with Daylight Savings time. \n\nTo know for sure, check your computer's time/date settings. For Windows PCs, double click the time in the lower-right corner. It'll bring up a box that'll have a "Time Zone" tab. If you go there, you should see the something like "GMT -xx:00", where the xx is a number of hours. Subtract that number (or add it, if the number is +xx:00), and that's the sent time.
