That's the amount of time that the New Goal Line Technology system has to inform the referee if the ball has crossed the line or not.
The first test phase, due to be carried in the next few months, will be conducted by the Swiss technology research institute EMPA.
"EMPA is a government-funded research institute," project leader Martin Camenzind said. "Our experience with football and Fifa started about 10 or 12 years ago with the quality concept of football testing.Thanks to our experience in football testing and long lasting collaboration we are very happy to be asked to do the goal-line technology project together with Fifa."
The tests will involve three sections to ensure that the systems can accurately and quickly inform the referee whether the ball has fully crossed the line.
Impact boards that will simulate a goalkeeper or defender clearing the ball away, and situations in which players could block the camera will also be recreated. There will also be tests done under floodlights.
The systems will eventually have to inform referees within one second whether the ball has crossed the line. Companies that pass the initial stage of testing will then undergo a second testing stage next year.
If one of the systems is approved, it could be used at the 2014 World Cup in Brazil.
The International Football Association Board has laid down four basic requirements that goal-line technology systems have to fulfil:
1. The technology applies solely to the goal line and only to determine whether a goal has been scored or not.
2. The system must be accurate.
3. The indication of whether a goal has been scored must be immediate and automatically confirmed within one second.
4. The indication of whether a goal has been scored will only be communicated to the match officials (via the referee's watch, by vibration and visual signal).
The first World Cup was played in 1930 .That will make it 84 years of World Cup history when Brazil 2014 kicks off.
And FIFA are giving that machine one second to come up with the right decision.
After what will be 84 years of some pretty horrendous human errors.
That sounds fair enough..............!
