On 1 November 1884, the Greenwich Meridian was adopted universally at the International Meridian Conference in Washington DC, USA. As a result, Greenwich Mean Time became the time standard and the 24 time zones were created. When did GMT time start? Discover gifts from the home of time As the […]
Precision – synchronized with atomic clock time Time.is is synchronized with an atomic clock – the most accurate time source in the world. The displayed time will normally have a precision of 0.02-0.10 seconds. What is the most accurate clock in the world? Atomic clocksAtomic clocks are the most precise […]
Greenwich Mean Time. The International Meridian Conference The conference established the Greenwich Meridian as the prime meridian and Greenwich Mean Time (GMT) as the world’s time standard. The international 24-hour time-zone system grew from this, in which all zones referred back to GMT on the prime meridian. What was the […]

UTC serves to accommodate the timekeeping differences that arise between atomic time (which is derived from atomic clocks) and solar time (which is derived from astronomical measurements of Earth’s rotation on its axis relative to the Sun). Why do we use UTC time? It’s used as the primary time measurement […]

Therefore this also became the start of the Universal Day. When was Greenwich Mean Time invented? On 1 November 1884, the Greenwich Meridian […]
Sir Sandford Fleming. In 1878, Sir Sandford Fleming (1827? 1915) developed the system of worldwide time zones that we still use today. He proposed that the world be divided into 24 time zones, each spaced 15 (fifteen degrees) of longitude apart (like 24 sections of an orange). Who came up […]
Since 1972, UTC is calculated by subtracting the accumulated leap seconds from International Atomic Time (TAI), which is a coordinate time scale tracking notional proper time on the rotating surface of the Earth (the geoid). Where did UTC come from? You might be wondering why UTC is the abbreviation for […]
