Laser metronome achieves record synchronization

Scientists have set up the world's most precise 'metronome' for a kilometer-wide network. The timing system synchronizes a 4.7-kilometer-long laser-microwave network with 950 attoseconds precision. An attosecond is a millionth of a millionth of a millionth of a second.
