At different times in the past, it has been calculated in different ways, including being calculated from noon ; [1] as a consequence, it cannot be used to specify a particular time unless a context is given. Because of Earth's uneven angular velocity in its elliptical orbit and its axial tiltnoon GMT is rarely the exact moment the Sun crosses the Greenwich Meridian [b] and reaches its highest point in the sky there. Gmt 1 event may occur up to 16 minutes before or after noon GMT, a discrepancy described by the equation of gmt 1. Noon GMT is the annual average the arithmetic mean moment of this event, which accounts for the word "mean" in "Greenwich Mean Time".

Increasing globalisation in the Victorian era meant a need to standardise time zones, as businesses began to operate across wider areas and world travel became easier with the advent of the railway. The Meridian Conference in , attended by representatives from various countries, led to the creation of the 24 time zones we use today. The zones are based on 24 longitudinal meridian lines that run from the north to south poles. The prime meridian, determined by the conference, runs through Greenwich, in the UK, giving us Greenwich Mean Time. Other time zones are counted to the east and west of this line, either plus or minus hours from GMT. Each country sets its own time zone within this framework, so some zones extend beyond the meridian for convenience, while others, like India, take on half hours. Kiribati even extended its time zone miles east in , to include Caroline Island in the same zone and, as it straddled the Date Line opposite the GMT meridian, the same date as the country's other islands.

Accordingly, at Liew further asserted that during the debate on the Malaysian Standard Time Bill on 21 December , it was stated that the difference in timezone between Sabah and Sarawak with Peninsula Malaysia has brought many problems. These include the wasting of official communication time of offices for about 2 hours a day. Furthermore, making the timezone of the whole of Malaysia the same despite East and West Malaysia being divided by the vast South China Sea was also touted as an initiative to further strengthen the ties of both regions. Moreover, the standardisation was also in line with international practice. Share your thoughts with us in the comments!

This is a list representing time zones by country. Countries are ranked by total number of time zones on their territory. Time zones of a country include that of dependent territories except Antarctic claims. France , including its overseas territories, has the most time zones with 12 13 including its claim in Antarctica. Many countries have daylight saving time , one added hour during the local summer, but this list does not include that information. The UTC offset in the list is not valid in practice during daylight saving time. Contents move to sidebar hide. Article Talk.

Several countries define their local time by reference to Greenwich Mean Time. Archived from the original on 14 June Although that instrument still survives in working order, it is no longer in use and now the meridian of origin of the world's longitude and time is not strictly defined in material form but from a statistical solution resulting from observations of all time-determination stations which the BIPM takes into account when co-ordinating the world's time signals.
