what is "GMT" ?

Question

IT IS SOMETHING RELATED TO TIMEZONES.

Answer 1

GMT STANDS FOR GREENWICH MERIDIAN TIME....

IT IS THE STANDARD SCALE ACCODING TO WHICH THE TIME OF OTHER COUNTRIES ARE RELATED...LIKE INDIA IS 5:30 HRS AHEAD OF GMT..SO IF YOU GO TO ANY OTHER COUNTRY THEN WE SET OUR CLOCK ACCORDING TO THE GMT OF THAT PLACE..IT HELP US TO CALCULATE THE TIME AT A PARTICULAR LATTITUDE

Answer 2

Greenwich Mean Time (GMT) is a term originally referring to mean solar time at the Royal Observatory, Greenwich in England. It is now often used to refer to Coordinated Universal Time (UTC) when this is viewed as a time zone, although strictly UTC is an atomic time scale which only approximates GMT in the old sense. It is also used to refer to Universal Time (UT), which is the astronomical concept that directly replaced the original GMT.

Noon Greenwich Mean Time is not necessarily the moment when the Sun crosses the Greenwich meridian (and reaches its highest point in the sky in Greenwich) because of Earth's uneven speed in its elliptic orbit and its axial tilt. This event may be up to 16 minutes away from noon GMT (this discrepancy is known as the equation of time). The fictitious mean sun is the annual average of this nonuniform motion of the true Sun, necessitating the inclusion of mean in Greenwich Mean Time.

Historically the term GMT has been used with two different conventions for numbering hours. The old astronomical convention (before 1925) was to refer to noon as zero hours, whereas the civil convention before 1925 and more modern astronomical and civil convention is to refer to midnight as zero hours. The more specific terms UT and UTC do not share this ambiguity, always referring to midnight as zero hours.

Answer 3

The full form of GMT is Greenwhich Mean Time.
It is a virtual longitude passing through London and helps in classifying the entire world in different time zones.

As one moves away from the GMT, the places on the eastern side are ahead in time while the places located on the western side of GMT are behind the time in GMT location.

Answer 4

GMT means Greenwich Mean Time

Answer 5

GMT refers to Greenwich Mean Time. Earth is divided into 24 time zones. The 180 degree longitude is taken as the International Date Line where one calender day ends and another begins. While crossing from east to west one gains a day and loses the same while travelling from west to east.

Answer 7

GMT stands for Greenwich Meridian Time or also known as Greenwich Mean Time .

Greenwich is in England where 0 degree longitude or the prime meridian crosses . From this , The time is derived .

Indian time is called IST which is +5:30 from GMT .
Extra(s):
IST stands for Indian standard time .

Answer 8

Greenwich Mean Time.

Greenwich is a place in England which is the standard reference point in time.

Example: Let's meet at 21:45 GMT. So meet me at the time in Greenwich time, not the time where u r at...So do some math and you'll know the time we'll meet.

Answer 9

That means GREENWICH MERIDIAN TIME because by international agreement, all the rest of the meridian, refer the difference of hours, by the first meridian described in history, and that is an imaginary line that divides in two, the village of Esatern London called Greenwich,
There is also located an observatory, that adjusts the precision of time, so all the other meridians, taje this pattern as "zero" or main reference....If something happened enywhere else in the world, they tend to cite GMT (the time of east london ) as a reliable reference

Answer 10

GMT stands for Greenwich Mean time. It is the reference point to which all time zones are set. It is so called on account of the fact that the imaginary meridian representing this reference zone passes through Greenwich in England. All time zones in the world are clocked + or - of GMT.

Answer 11

GMT is Greenwich Mean Time.

It is called GREENWICH Mean Time because the Prime Meridian (0° longitude) was designated to run through the observatory in Greenwich, England.
