Not satisfied with the accuracy of the "quantum logic clock" (which only gains or loses one second every 3.7 billion years), the National Institute of Standards and Technology (NIST) and JILA have unveiled an even more precise timekeeper. The strontium lattice clock sets new standards for precision and stability, only gaining or losing one second about every five billion years.
