What does greenwich time means?

Question

What does greenwich time means?

Answer 1

It refers to Greenwich England where the marker 0 for modern time was set. Originally it had a lot to do with navigation on the sea, but in the modern era it has just become a marker for keeping our clocks straight. Lookup "time zones" on wikipedia, I'm sure that they have a very detailed explaination.

Answer 2

Greenwich MEAN time is set from the Greenwich Meridian which is the imaginary time line from which the worlds time is set.

Answer 3

The whole world's time is set in relation to the central point at the Observatory in Greenwich, South East London. Greenwich meantime aka GMT is THE actual time and is totally accurate.

Answer 4

The time in Greenwich, England. It is a standard to which all other times are related.

Answer 5

What does your question mean? Are you looking for something other than all world time being based on the prime meridian which passes through Greenwich, London? Everything to the east is + GMT and everything to the West is - GMT

Answer 6

It means the time at Greenwich London.  Greenwich is also Longitude and Latiude point 0, which is a system ships use to navigate.

Answer 7

Those talking about Greenwich Mean Time are correct - it is the time at the O meridian, without regard to Daylight Savings Time/British Summer Time. Currently the local time in Greenwich and GMT are the same, as its winter, but in summer local time is 1 hour ahead.

Some people quote UTC, or Universal Co-ordinated Time instead. It is the same as GMT.

Answer 8

"Greenwich Mean Time" (GMT) is a term originally referring to mean solar time at the Royal Observatory, Greenwich in England.

As the United Kingdom grew into an advanced maritime nation, British mariners kept their timepieces on GMT in order to calculate their longitude "from the Greenwich meridian", which was by convention considered to have longitude zero degrees.

Greenwich Mean Time was adopted across the island of Great Britain by the Railway Clearing House in 1847, and by almost all railway companies by the following year. It was gradually adopted for other purposes, but a legal case in 1858 held "local mean time" to be the official time.

time zone of Greenwich, London.  The time zone from which all others are calculated.

(b/c they don't observe daylight savings time, it's always constant).

Answer 10

Greenwich Mean Time is otherwise known as universal time. When Britain was the centre of the universe (or at least the world) back in the day we got to tell everyone else what time it was.

Answer 11

The time in Greenwich, England.

--------------------------------------...

There are 25 integer World Time Zones from -12 through 0 (GMT) to +12. Each one is 15° of Longitude as measured East and West from the Prime Meridian of the World at Greenwich, England.  Some countries have adopted non-standard time zones, usually 30 minutes offset which have a * designation.

Each Time Zone is measured relative to Greenwich, England. There are both civilian designations which are typically three letter abbreviations (e.g. EST) for most time zones. In addition there are military designations. These use each letter of the alphabet (except 'J') and are known by their phonetic equivalent. E.G. Greenwich Mean Time (civilian) or Z = Zulu (military and aviation).
