Greenwich, London is at Longitude 0 and latitude N51.48 degrees. Greenwich is the universal reference point for time zones called Greenwich Mean Time or more commonly GMT. Most time zones are based on this reference as a number of hours and half-hours "ahead of GMT" or "behind GMT".
Accra, Ghana, Africa
Amsterdam is (Greenwich Mean Time) GMT +1 hour, ie. 1 hour ahead of Greenwich, England. US Pacific Time - is (Greenwich Mean Time) GMT -8 hours, ie. 8 hours behind Greenwich, England. Oregon is 9 hours behind Amsterdam. (Daylight savings not taken into account.)
The clock at the Greenwich Observatory, Greenwich, London, England set the standard time (Greenwich Mean Time (GMT)) and has done for hundreds of years. The Greenwich Observatory is on the Greenwich Mean Line and initially set where 0o Latitude is.
Australia has 3 Time Zones. * Eastern is (Greenwich Mean Time) GMT +10 hours, ie. 10 hours ahead of Greenwich, England. * Central is (Greenwich Mean Time) GMT +9.5 hours, ie. 9.5 hours ahead of Greenwich, England. * Western is (Greenwich Mean Time) GMT +8 hours, ie. 8 hours ahead of Greenwich, England. Canada has 5 Time Zones. * Atlantic Time - is (Greenwich Mean Time) GMT -4 hours, ie. 4 hours behind Greenwich, England. * Eastern Time - is (Greenwich Mean Time) GMT -5 hours, ie. 5 hours behind Greenwich, England. * Central Time - is (Greenwich Mean Time) GMT -6 hours, ie. 6 hours behind Greenwich, England. * Mountain Time - is (Greenwich Mean Time) GMT -7 hours, ie. 7 hours behind Greenwich, England. * Pacific Time - is (Greenwich Mean Time) GMT -8 hours, ie. 8 hours behind Greenwich, England. (Daylight savings not taken into account.)
Portugal (Mainland and Madeira) is in the Western European Time Zone. Western European Standard Time (WET) is Greenwich Mean Time (GMT). Like most states in Europe, Summer Time is observed in Portugal, where the time is shifted forward by 1 hour; 1 hours ahead of Greenwich Mean Time (GMT+1). After the Summer months the time is shifted back by 1 hour to Western European Time (WET) or (GMT). The Azores are in the Azores Time Zone. The Azores Time Zone is Greenwich Mean Time -1 (GMT-1).
Australia has 3 Time Zones.Eastern is (Greenwich Mean Time) GMT +10 hours, ie. 10 hours ahead of Greenwich, England.Central is (Greenwich Mean Time) GMT +9.5 hours, ie. 9.5 hours ahead of Greenwich, England.Western is (Greenwich Mean Time) GMT +8 hours, ie. 8 hours ahead of Greenwich, England.The USA has 6 Time Zones including Alaska and Hawaii.Eastern Time - is (Greenwich Mean Time) GMT -5 hours, ie. 5 hours behind Greenwich, England.Central Time - is (Greenwich Mean Time) GMT -6 hours, ie. 6 hours behind Greenwich, England.Mountain Time - is (Greenwich Mean Time) GMT -7 hours, ie. 7 hours behind Greenwich, England.Pacific Time - is (Greenwich Mean Time) GMT -8 hours, ie. 8 hours behind Greenwich, England.Alaska Time - is (Greenwich Mean Time) GMT -9 hours, ie. 9 hours behind Greenwich, England.Hawaii Time - is (Greenwich Mean Time) GMT -10 hours, ie. 10 hours behind Greenwich, England.Depending on which part of Australia you are in, Florida is 13 to 15 hours behind. (Daylight savings not taken into account.)All of Florida and about a third of Australia observe Daylight Saving Time, but they do so in opposite halves of the year since they are in opposite hemispheres. This results in a two-hour variation through the year in the time difference between, for example, Miami and Sydney.Florida's Daylight Saving Time begins in mid-March and ends in early November. Australia's begins in early October and ends in early April. Western Australia, the Northern Territory and Queensland do not do Daylight Saving Time.So when it's these times in Florida...6 AM Central Standard Time= 7 AM Central Daylight Saving Time= 7 AM Eastern Standard Time= 8 AM Eastern Daylight Saving Time... it's these times in Australia...= 8 PM Western Standard Time= 8:45 PM Central Western Standard Time= 9:30 PM Central Standard Time= 10 PM Eastern Standard Time= 10:30 PM Central Daylight Saving Time= 11 PM Eastern Daylight Saving Time
Holland is always an hour ahead of the UK. In summer most of Europe change the time to move it forward an hour. This is called Daylight-saving. Both the UK and Netherlands do this so the time difference remains the same.
Gran Canaria, the second most populous island in the Canary Islands, has the same time as England. Gran Canaria is in the Western European time zone, and England is in the British Summer Time zone from March's last Sunday to October's last Sunday and on Greenwich Mean Time (GMT) the rest of the year. Both locations observe daylight savings time.
Greenwich Mean Time (GMT) is the time of day at any point on the Greenwich meridian (the zero degree line of longitude). It is from this time that all other time zones on earth (+ or -) are compared therefore if you want to communicate things that happen all round the earth you use GMT to communicate this (rather than your local time) to avoid confusion and the need for calculations.
UTC stands for "coordinated universal time" (see link), and is the more modern name for what used to be GMT (Greenwich mean time).Coordinated Universal Time (UTC) is a time standard based on International Atomic Time (TAI) with leap seconds added at irregular intervals to compensate for the Earth's slowing rotation.[2] Leap seconds are used to allow UTC to closely track UT1, which is mean solar time at the Royal Observatory, Greenwich.The difference between UTC and UT1 is not allowed to exceed 0.9 seconds, so if high precision is not required the general term Universal Time (UT) may be used.[3]In casual use, when fractions of a second are not important, Greenwich Mean Time (GMT) can be considered equivalent to UTC or UT1. Owing to the ambiguity as to whether UTC or UT1 is meant, GMT is generally avoided in technical contexts.[3]Time zones around the world can be expressed as positive or negative offsets from UTC; UTC replaced GMT as the basis for the main reference time scale or civil time in various regions on 1 January 1972.[4]
