Gmt 2 time zone

The Rolex GMT-Master series has been the last word in luxury travel watches for more than six decades. To do so, Rolex borrowed the rotating bezel concept they had introduced on their Turn-O-Graph a couple years before, marking it with a hour scale, gmt 2 time zone, and fitting the dial with an additional hour hand, geared to run at half speed. To read a secondary time zone, the bezel had to be turned to line up the numerals with the GMT hand.

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.

Because of Earth's uneven angular velocity in its elliptical orbit and its axial tilt , noon GMT is rarely the exact moment the Sun crosses the Greenwich Meridian [b] and reaches its highest point in the sky there. This event may occur up to 16 minutes before or after noon GMT, a discrepancy described by the equation of time. Noon GMT is the annual average the arithmetic mean moment of this event, which accounts for the word "mean" in "Greenwich Mean Time". Originally, astronomers considered a GMT day to start at noon, [d] while for almost everyone else it started at midnight. To avoid confusion, the name Universal Time was introduced in to denote GMT as counted from midnight. The term GMT should thus not be used for purposes that require precision. As the United Kingdom developed into an advanced maritime nation , British mariners kept at least one chronometer on GMT to calculate their longitude from the Greenwich meridian, which was considered to have longitude zero degrees, by a convention adopted in the International Meridian Conference of Synchronisation of the chronometer on GMT did not affect shipboard time, which was still solar time.

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. While the movements have been changed and upgraded since then, the basic principle is still the same. News Datablog.

For example, if a person who lives in California is currently in New York on a business trip, they can read the current time in New Yorkon the dial as normal, while the hour hand shows them the time back home in California against the accompanying hour scale on the bezel. This gives control over the main hour hand, which jumps forwards or backwards in one-hour increments. They can then read the current time normally off the dial, and their home time off the corresponding numeral that the hour hand points to on the bezel. The pair of watches shared a movement throughout most of their respective histories, right up until their most recent iterations.
