What is The time difference betweeN GMT and CET?

Answer 1

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]

Answer 2

GMT - or Greenwich Mean Time is the 'standard' by which all time zones around the world are measured. The 'modern' name for GMT is Universal Time Constant (UTC). Greenwich is a suburb of London - the capital city of England in the UK.

DST - or Daylight Saving Time, is a change that countries make to their 'normal' time, in order to make the most of the amount of daylight available. It doesn't actually 'save' daylight - it simply moves the times of sunrise & sunset forward one hour. DST is not universally applied to every country around the planet - but most countries do observe some equivalent of it.

Answer 3

CET = GMT + 1

so, 15:00 CET = 14:00 GMT

Answer 4

Central European Time (UTC+1) is 1 hour ahead of Greenwich Mean Time (UTC).

Answer 5

CET (Central European Time) is one hour ahead of GMT (Greenwich Mean Time).

Answer 6

The time difference between Greenwich Mean Time (GMT) and Central European Time (CET) is one hour. CET is one hour ahead of GMT.
