GMT Games
GMT Games is a California-based wargaming publisher founded in 1990. The current management and creative team includes Tony Curtis, Rodger MacGowan, Mark Simonitch, and Andy Lewis. The company has become well known for graphically attractive games that range from "monster games", of many maps and counters, to quite simple games suitable for introducing new players to wargaming. They also produce card games and family games. "The Washington Post" called GMT "the modern hobby's highest-profile wargame publisher".
International Meridian Conference
By the 1870s there was pressure both to establish a prime meridian for worldwide navigation purposes and to unify local times for railway timetables. The first International Geographical Congress, held in Antwerp in 1871, passed a motion in favour of the use of the Greenwich Meridian for (smaller scale) passage charts, suggesting that it should become mandatory within 15 years.
In Britain, the Great Western Railway had standardised time by 1840 and in 1847 the "Railway Clearing Union" decreed that "GMT be adopted at all stations as soon as the General Post Office permitted it". The Post Office was by this time transmitting time signals from Greenwich by telegraph to most parts of the country to set the clocks. By January 1848, Bradshaw's railway guide showed the unified times and met with general approval, although legal disputes meant that it was not until 1890 that GMT was formally established across the UK.
