In 2000, Greenwich Electronic Time - known as GeT - was initiated in Britain to act as an international standard for all electronic commerce.
The idea of Get is to provide a common standard for all electronic commerce around the world.
All e-mail messages and e-commerce transactions already carry a 'time stamp' based on Co-ordinated Universal Time - the modern equivalent of GMT. But most computer clocks have software which converts e-mail and message dates into local time.
The move will provide a single time standard for worldwide Internet traders and users around the world in the same way that Greenwich Mean Time has helped travellers to keep time since 1884.
